Package more Maemo packages and switch upstream to https://github.com/maemo-leste

Package hildon-home and dependant packages.

Current Maemo development happens in https://github.com/maemo-leste. The repos from https://github.com/fremantle-gtk2/ were cloned there and fremantle-gtk2 organization likely won't be used anymore, so change all the Maemo packages to fetch from maemo-leste instead.

Most of the current changes in the repos are changes to Debian packaging, which have no affect on us, so I didn't edit revision to avoid extra rebuilds. Only hildon-desktop and iphbd are bumped to new revision due to code changes.
