Release v0.75m

• Stormrider/hunter no longer heavily self-damages on air-to-air combat.
• Several palette bugs were fixed on the new aircraft.
• Removed duplicate desertconquer map.
• APC now has eject on death for its cargo. This is to test if this desyncs in multiplayer, which happened in the past.
• MAD Tank has been reworked. Now it causes seismic shocks that slow down all ground units in the area. No more damage dealt. Can stack up to 3 times. I forgot to update the description.
