native OSX improvements

[Antoine Martin]

Using igemacintegration it should be possible to:

• integrate into the mac menu
• integrate into the dock
• prevent having 2 icons (one for python and one for our app)

There must also be away to do the auto-start on the Mac.

Done part of it in r1750

Still need to:

• trim the menu
• catch quit and fire our own quit handler
• fix the drop down menu attached to the gtk.StatusIcon (doesn't always react to mouse)
• deal with too many menus to fit on screen, etc...

[Antoine Martin]

Trimmed the menu and added quit handler: r1758

This will do for now, moving to 1.1 release.

• Fixed the "double-dock" issue (was spawning new process rather than EXECing!): r2594
• Add more VNC bits (vncconfig, vncpasswd): r2603
• Try to place notifications near our status icon: r2607
• Updated nxproxy to latest 3.4 (+latest nxcomp lib): r2605
• Starting to build a PPC version: r2578, r2577 and r2580

Since the gtk.StatusIcon is a bit flaky on macosx (sometimes requires multiple clicks to respond as expected), maybe we should use native calls, pointer ​here

There's still the issue of Xpra coming up with its own icon in the doc, which does not respond to actions... unfortunately the Mac OSX API is just total garbage and all the "solutions" are just hacks (see this good write up: ​feature requests versus the right way to do it)

[Antoine Martin]

Xpra now uses its own dock icon, StatusIcon issues are tracked in #153
