Implement battle time bar attacking within range

The main debug drawing elements have been moved to debug.c to avoid
cluttering up the main game file. The downside is that thus far the debug
values only track values post-update.

We have a notion of begin attack and end attack to allow code to drive the
animation system and apply effects after an attack animation has
completed.
