chat: + added timestamps (can also be css styled and disabled) + allow exchanging stylesheet by just dragging a *.css file into the chat widget! + /saveStyleSheet command for keeping the applied stylesheet for future runs + /discardStyleSheet to reset to the saved/default stylesheet Note: I noticed command auto-completion is broken, don't know since when. annoying.

minor cleanups, mostly in own code

* fixing my hat preview bug nemo pointed out (thanks!) + cleanup of edit page loading, should speeed up application startup a bit.
