[log] Map files (continued)

I added an alternate way to define the starting units in a game. Here is an example from solo map 2:

player 10 10 b1 townhall farm peasant 2 footman archer c1 farm

This line will add a starting slot for one player (human or computer) with 10 gold and 10 wood, and, at b1, 1 town hall, 1 farm, 1 peasant, 2 footmen, 1 archer, and, at c1, 1 farm.

The map files for solo maps are complete, except for the triggers and timers, which is the next step.
