Multi Stage Utilia a1

Large amount was changed in the layout; Australium pickup location and capture area moved farther apart. Stage 2 is being created by @Lain

• Added a whole new area to the inside of the mountain.
  • Added due to complaints that the map was too small and fights where too short.
  • Due to this new area, I have moved the Australium Capture zone into the mountain. This should make it more difficult that previously.

• Added team colours to the structures.
• Changed "Intelligence" signs to "Australium" ones.
• Big optimization pass.
• Added bulletblock to the bridge that was allowing splash damage to pass through it.
• Changed the side route at mid so other classes can use it.
• Added pillars to the bottom area.
  • Done because this area was very flat and open.
• Added signs at the spawn that indicate where the capture point and Australium are.
• Moved spawn closer to the mid slightly.
