Beta 4.

- Fix Dispersion Pistol altfire not ending early when releasing the button.
- Dispersion Pistol now changes fire speed based on upgrade level, as intended.
- Reduced Razorclaw twiddle animation frequency, it was getting annoying.
- Impaler altfire now doesn't work underwater, as intended.
- Impaler crystals deal less damage when underwater.
- Impaler no longer loses charge underwater while the crystal is unloaded.
- Impaler beam no longer homes in onto friendlies.
- Fixed missing Impaler melee obituary.
- Flamegun disallows firing while underwater, to prevent wasting ammo uselessly.
- Flares and Seeds can be stacked until int.max (give cheats and whatnot are still capped at 20 though).
- Fixed Minigun not displaying the bullet box ammo icon in the 0.83 hud.
- Fixed mouse input in the main menu at high resolutions (wasn't accounting for scaling, oops).
- Added "<item> selected." messages. Dunno if DT will need this too.
- Light Sentry now uses the more reliable native IsHostile() function to detect targets.
- [flak_m] Added "<weapon> has no ammo." messages.
