Fixes for player being unable to boost/walljump on map change.
Boosting and walljumps have separate cooldowns now, so you can still jump right after finishing a boost.
Spreadguns dropped by enemies will also drop some spare ammo.
Fix health numbers not being rendered when invulnerable.
Fix Invinciball not displaying the invulnerable healthbar.
Fix a targetter crash due to an incorrectly written conditional check.
Attempt to reduce the lag caused by excess damage numbers.
- Deep Impact implemented (ammo display not done yet, so it's just text).
- More HUD features: enemy healthbars, omnisight, damage/health/score numbers.
(not yet tweakable, will add options later. also omnisight's usable line
highlighting currently has incorrect positioning, will fix later too).
- Fixes 'n stuff.
- Library text adjustments.
