DAGGER_Fixes

Part of DAGGER Systems, for the 2/75 Ranger Regiment Realism Group.

Unofficial game 1.9 compatibility fixes:
- AUS_CORE: one of its scripts re-declares three weapon fire modes (SALVO, RIPPLE, SEQUENTIAL) that game 1.9 now declares, so scripts can't compile. This patch replaces that script with one that only adds AUS_CORE's minigun modes (AUTO, BURST, SINGLE).
- Game Master FX: it ships an old copy of a game script that 1.9's tree cutting and building now depend on. This patch restores the game's own 1.9 version.
- WCS_Core: its XP script re-declares one reward type (SQUAD_KILL_ASSIST) that 1.9 now declares. This patch removes that one entry. Included with permission from Worst Case Scenario.

Requires AUS_CORE (TheAussieMerc), Game Master FX and WCS_Core (Worst Case Scenario). All credit goes to their authors.
Temporary: each fix will be removed once its mod is updated for 1.9.
