- Added per-player resource pool and modified the GUI and entity scripts to work with it. - Modified unit creation functions so the unit is always assigned a player before firing its initialize event, so that this event can deduct population, etc from the right player. - Fixed various small bugs, like a unit not cancelling all of its queued items when it dies, or buildings not costing anything. This was SVN commit r3998.
