v0.2.43+70 *SHINOHARA*

New enemies: ZOMB is slow but dangerous up close, ARCHR is fragile but lobs missiles

New audio looping system, and new sounds (this is still in progress, so feedback much appreciated). Many new sounds are implemented but currently silent (i.e. they need to be found and made to sound good in the overall audio mix).

Types of entities can have distinct shapes on the map. This help identification in the midst of action.

Entities now respond more realistically to explosions (angular impulse)

Fix audio error on game exit

Fix audio error that makes music resume even when it should be off

Improvements to developer/modder tooling (to be included with game later)
