Ubiquity installer should be in favorites for livecd

[Paul Larson]

It's hard to launch the installer for Ubuntu Moblin Remix. "Install Ubuntu" should be proeminent in the Ubuntu Moblin Remix live session. It should at least appear in MyZone and ideally also be in an expanded zone of Applications or at the top of Applications.

Workaround:
- click the top panel's "Applications" icon on the top right
- expand the "Settings"
- open "Install Ubuntu" (Ubiquity)

Proposed release notes:
Ubuntu Moblin Remix developer preview has no installer shortcut on the welcome screen
--
To start the installation of the Ubuntu Moblin Remix developer preview from the live session, open "Install Ubuntu" under Applications > Settings. (See Bug:439656.)

This can be fixed in casper. I have the beginnings of the change done.
