Roster now has scrollbar.  Reorg of UI to use LayoutManagers right.
Roster is now the only Side selector and handles loading and removing
sides.
Add scrollbar to tournament view, rewrote to use TexaPane and html
formatting
Bug fix; show robot errors menu item was not wired to the world, only
the game.  Took the opportunity to remove a bunch of throws declarations
that were not necessary.
Better sync between EDT and game thread for screen refreshes, portal
doesn't stutter on unlimited speed anymore.
Fixed the bug that was making the edges of the portal disappear at
certain times.
Removed some commented-out code and TODOs that didn't apply anymore.
