Add DlgDeveloperTools, a dialog with various useful debugging tools.

* A controls tab where you can see and edit Mixxx's controls directly.
* A stats tab where you can see the stats (e.g. average soundcard callback
  durations) that Mixxx tracks in realtime.
* A log tab where you can see the Mixxx log without having to go find it on the
  filesystem.

The tables are set to update at 2FPS which seemed like the right balance between
CPU overhead and interactivity to me.
