[Confluence] Add 'Events' to Home screen's 'System' submenu.

[ksooo]

As discussed at DevCon, this adds an entry 'Events' to Confluence home screen, 'System' submenu. The new entry is only visible, if "Settings->System->Logging->Enable event logging" is checked. When the new entry gets selected, the event log window opens, like if started directly from "Settings->System->Logging->Show event log"

@ronie, @Montellese mind taking a look.

[ronie]

nice, no objections from my end.

[phil65]

yup nice, although I only can remember a discussion to put Eventlog into "System information" window? But perhaps that's related to my constant hangover there. :)

[ksooo]

System information windows does imo not really make sense, because the windows there are all "passive" - no selectable content, just non-interactive read-only stuff there. Event log window is different - interactive, you can do "things" with the event log entries.

[phil65]

True, but it still makes much more sense than to put it into settings imo ;).
anyways, not related at all to this PR. I'd say press the green button, @ronie

[Montellese]

Already forgot about this so thanks for remembering and getting it done.

Is there no potential harm in changing the id of the old entry?

[ronie]

nope, it's not a problem here. it's only an issue when:

• it's built-in id
• the id is evaluated elsewhere in the skin to conditionally display stuff
• two visible controls in the same window would now have the same id

[razzeee]

Thanks.
Figured it might cause problems when the ID might also be used in the C++ code. It's not the case here, but to be safe 100% I thought it might be nicer, to not change ids of old elements.
