UI cleanup, and a new take on ammo

Sharper characters

All 92 character textures now have upscaled versions.

Clean art everywhere

The cyan-keying fix for inventory icons now covers all of the original interface art, so no more cyan squares behind menu pieces.

Ammo that refills itself

Weapons no longer use the template’s magazine-and-reserve ammo. Each weapon has a single pool that reloads itself on a timer once it runs dry, and you can start a reload early at any time. The ammo visibly counts back up during the reload. Switching away mid-reload loses the progress, so a weapon you swap back to starts its reload again.

HUD

The weapon panel and gameplay HUD were reworked to match.
