[log] Triggers and starting menus

Started to think about triggers for solo maps (or even multiplayer missions, why not?). An example of trigger (from solo map 2) is:

trigger computer 1 timer 1 order a2 1 footman go a1

It means: add a trigger for computer 1 so after 1 * time_coeficient seconds, order 1 footman situated in a2 to go to a1.

Another trigger (from solo map 1):

trigger player 1 if_has 2 farm 1 barracks then victory

It means: add a trigger for player 1: if he has 2 farms and 1 barracks then he wins.

Started to think about the way games should be started in beta 9. Here is a draft of the menus:
