Add a new attribute called "_hidden_activities" to BundleRegistry,
so it can be used in other scenarios, such as when bundles are
installed in runtime to determine whether or not bundle should be
favorite looking at this list.

Add "activities.hidden" file with the bundle ids of Log and Terminal
activities, as suggested in [1]. Deployments can later customize it
via patching the sugar package or via OOB.

Parse "activities.hidden" file and use the bundle ids to determine
whether or not thw newly scanned activities should be favorites.

Remove the "activities.defaults" file because is no longer
used with the new approach.

Remove "self._last_defaults_mtime" from BundleRegistry
because is also no longer used either.

Previously, the shell determined if an activity was a favorite by
looking into the "favorite_activities" JSON file or by checking
the "activities.defaults" file.

The "activities.defaults" probed to be confusing and perceptively
incosistent [1]. During the discussions it was suggested that we
could provide a list of activities that should NOT be favorites
as defaults.

This patch series remove the use of the "activities.defaults" file
and intead introduces the use of a new "activities.hidden" file.
With this new approach, all activities are be considered favorites
unless their bundle ids are listed in the "activities.hidden" file.

This first patch extends the JSON format of the "favorite_activities"
file to track activities that have been un-favorite by the users so
we can later override the values of the "activities.hidden" file.
This is because user preferences should take precendence over default
values.

Use different Gtk.TreeViewColumn for each favorite column,
otherwise only the fist one can be clicked and prevents
populating the other home views.

Slightly cleanup that code.

Hide power control panel if powerd missing

The extreme power saving mode was removed a long time ago, but the
search terms were not updated.

On commodity hardware the power control panel does nothing useful.

Now, if powerd is not present, the CLASS global is not set, causing the
panel to be omitted from the control panel.

The message about missing CLASS is demoted from error to debug.

Load the brightness module earlier in the shell startup process
in order to restore the brightness level before any other screen
shows up, ie., the intro screen.

Watch the specific brightness file instead of watching the whole
device directory and drop the use of WATCH_HARD_LINKS because is
not necessary.

This patch fixes the brightness monitor in Fedora 18.

…s/sugar into samdroid-apps-overlay-scroll-try3

This commit disables overlay scrolling in Sugar.  Although this should
be set in the sugar theme, that is not possible.

Setting the environment variable disables the overlay scrolling for
both Sugar Shell and all sub processes (eg. activities).

By setting an environment variable, this is ignored by Gtk versions
less than 3.16.

For consistency with other modal dialogs such as view source and control
panel, add a handler to translate escape key into stop button.

On most XO laptops the firmware version doesn't have the engineer's
build number appended, and this results in "Q7C05   with 0.5.01" shown.

Strip the trailing whitespace before using the version number.

Change the star color on hovering cnfuses to the user,
because think the favorite state has changed.
This can be seen in the activities list view, in the Journal listview,
and in the Journal detail view.

Now the palette is created by the treeview, we don't need
signals in the icon.

These changes were introduced with the TreeViewInvoker

The signals datail-clicked and volume-error, now are triggered
in the TreeView class, and need be connected.

Use the TreeViewIvoker, need move the creation fo the palettes,
from the CellRendererIcons to the TreeViews.
This simplify the code, and allow create the palettes only in the moment
that is needed. In particular, in the Journal, the palette creation is expensive,
and previously was created in the moment the mouse was over the icon,
not matter if the palette was used or not. This was the origin of bugs like [1]

Using the ScrollingDetector, we can avoid expensive drawing
operation unneded while scroll in the CellRendererIcons.
This patch attach the scrolling detector to the treeviews in the Journal
and in the Activities List.

Connect to Brightness.changed_signal to update the progress bar if

Add a delay to the changes triggered by the progress bar in the display
frame palette.

This is necessary because calling to external tool is slow and because we
do not need to update the screen brightness for every bit of increment,
while the bar is still being changed.

Use a GFileMonitor to track external changes done to the backlight
device.

This is required for detecting changes made to the device from external
power managers and to workaround missing keyboard events in the XO.

Ignore "external" changes triggered internally.
