updates from 0.7.3 + new binaries

This release focused on making a "preview" of the acceleration / speed / junction deviation modification available. This is done by transcoding the UP data back to g-code and call an external g-code viewer (e.g. Simplify3D).

Newly does this release include this binaries for all platforms:

tool	description
up3dstatus	controls and shows information about current print status
up3dcapture	captures current print job axis positions
up3dgcode	converts the captured data back to g-code for viewing
up3dconvg	converts UP machine code to g-code for viewing

Note: please focus on testing these tools on Linux as well as Windows platform, since the main development
runs under OS X.

The transcoder is updated to https://github.com/MaikStohn/UP3D/releases/tag/v0.7.3

A new version of the OS X based GUI for the transcoder allows to launch a configurable external preview. The app bundles all new binary tools from this release.

Edit 07-Oct-2016: new myUP App 0.0.29 includes now selectable filament and temperatures for extrude/withdraw
Edit 09-Oct-2016: new myUP 0.0.30 correct time display if print time is >= 1h
Edit 27-Oct-2016: new myUP 0.0.33 count down during layer print, corrected remaining time rounding issue
Edit 27-Oct-2016: new myUP 0.0.34 added dialog constrains for resize

V0.7.2 adds scalable acceleration, speed, junction dev.

The up3dtranscoder gets 3 more parameters to scale the defaults for acceleration, speed and junction deviation. This allows to control how smooth or fast the printer should operate.

Recommended values are:

	a_factor	v_factor	junction deviation
very smooth	5	20	0.05
smooth	10	50	0.05
normal	20	100	0.05
fast	100	100	0.05
very fast	100	100	0.1

Please note that your slicer determines the maximum speed you can achieve. The transcoder applies the physical acceleration and speed limits. To get a better understanding on those settings, set first your slicer to a fast printing mode of e.g. 80mm/sec and then limit acceleration and speed via up3dtranscode parameters.

This release addresses also PID support for UP Plus printers #2 . Since issue #3 is not yet resolved, your milage using UP Plus with this tools may vary. Feedback is always welcome.

There is myUP a OS X GUI preview attached which makes use of the above settings. So if you are running under OS X give it a try and send some feedback.

Edit 3-Oct-2016 : new myUP Version 0.0.25

V0.7.1 Infill Shift Fix Pre2

This is the first release under the new Organization on Github. This release fixes a calculation error on the move vectors, which resulted in shifted infill pattern not centered to the perimeters.
