Ported Allies 01 to the New Lua API

Changes include:
* Added an objectives panel with proper instructions that get updated during the mission.
* The ore management hack in TickIdle has been removed (as in the desert-shellmap).
* The soviet base alert got now got a real alarm sound to make enemy behavior easier to understand.
Alert is a bit too generic for this. There are other alert sounds like bleep6.aud.
