Review request for Calligra, Sven Langkamp and Yue Liu.

Description
-------

The palette bar below the canvas view in Karbon no longer shows a palette for me. And the menu in the popup with palettes to select from is empty.

Seems this is because a KoResourceServerAdapter needs to explicitely called `connectToResourceServer()` on to make it listen to changes in the resourceserver. This seems to be like that forever (2007, see 6603f52fa974ae5ec85f9112a1b74bb1b7f05fe6). I could not find what has changed there recently that broke things.

Attached patch restores the old behaviour again for me, having the list of all installed palettes in the menu of the bar, and one preloaded.
