Update app-install-data

The app-install-data package is used by gnome-app-install and adept_installer. It is a collection of desktop files/icons with added meta-information.

Usually a up-to-date version can be found at: http://people.ubuntu.com/~mvo/gnome-app-install/ (updated regularly).

If not, it is generated on a system with a full mirror like this:

<go to the app-install-data source tree>
$ rm menu-data/*.desktop menu-data/icon/*
$ util/getMenuData.py /src/path/to/pooldir
$ util/addPopconData -d menu-data/
$ bzr add menu-data/
$ bzr diff
$ bzr commit
$ bzr-build-package -S
dput ...
