[packagekit] Release soon

[Richard Hughes]

Guys, girls,

I'm planning to release 0.2.3 at the end of the week. Please can you
make sure that anything you want in the release is present in the
GNOME_PACKAGEKIT_0_2_X and PACKAGEKIT_0_2_X release branches.

When we've got the 0.2.3 release out of the door we can start working on
the 0.3.0 release, but a lot of the backends need minor tweaks just to
get compiling and working.

Thanks.

Richard.
