Made some fixes to the board rendering code.
The parent categories now print out above their respective group of categories.
This code works with the assumption that parent categories will always be above neighboring categories.
It will still print if they aren't but once #154 is done we shouldn't be able to get into that state.
I also made some small board related fixes.
The route code is now in its own controller and at André's request I made the 'null' swimlane only print out if there are actually cards in it.
