Subject: [PATCH] Add support for deskbar mode.

If the plugin's size needs allow it, set plugin into "small" mode.

That alignment stuff in the panel multi-row mode seems to be buggy.
I tried to get it working as good as possible, but there are some weird,
unexpected things happening with some configurations.
