So much stuff to do, so little time.
CaelumEngine:
* Included a version constant.
* Modified the start/stop cycle.
* Now with null checking for threadRender.
Implmented IUpdatable. Why? No clue.
ThreadStoppable:
* Renamed update() to rawUpdate().
* Implemented isPaused().
* stopThread() and setPaused() are no longer final.
ThreadTimed now implements IUpdatable, for consistency's sake.
Began to work on networking, no clue why.
Moved all thread classes back to their respective packages.
