Merge lp:~widelands-dev/widelands/ui_improvments into lp:widelands

Some fixes and features related to ui. See linked bugs and commit messages for details.
I tried to make commits as atomic as possible, so they could be merged separately if needed.

[SirVer (sirver)]

No complaints from my site. Merged!
