Merge lp:~brunonova/software-properties/update-apt-on-exit into lp:software-properties

[Bruno Nova]

Fixes Bug #1075537 (and, indirectly, Bug #782953 it seems).

The apt cache was not being updated on exit, because the "modified_sourceslist" variable in the file "softwareproperties/gtk/SoftwarePropertiesGtk.py" was not being set correctly (it was never set to True). This was fixed, I hope.
Tested in Ubuntu 13.04 by replacing the installed version of the file (in /usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py) with this new one. It worked in my tests (not many tests), and update dialog appeared on exit.

Apparently, this also fixes Bug #782953 in the Software Center.
When software-properties-gtk is run by Software Center, it "grabs" (and hides) the update dialog and shows the update progress inside the Software Center.
It, then, runs "update-apt-xapian-index" correctly.

Thanks, this looks good.
