Code review comment for lp:~widelands-dev/widelands/fix-dropdowns

Most travis builds green, two fail as of test_inputqueues.lua

Compiled. To test:
* in MapEditor
** Widht/Height dropdowns (new Map)
** Widht/Height dropdowns (resize Map)
** Number of Players dropdown
* Filter in news overview
* Which examples of minimzed UniqueWindows can you give me?

* How can I find the hotkeys and test them?
* Improved SyntaxErrorImpl - no idea how to test this :-)
  Can I break som RichText in an easy way?

* Sure we want to log every (Lua Button) keypress?

Nice refactoring of boring code :-)

Will no test the Lua part -> next Branch.
