Carry-alls are completed.

Carry-alls are completely done now.

Fixing up the code that moved the unit to the nearest tile was easy as cake. Didn't go much wrong there. After that I added a small SignalPickup() function, which took a reference to the carry-all which was fulfilling the request, so that the unit can cancel the request at all times without searching through all units.

After that I finished the tiny bit of work that made the carry-all fly to it's end, drop the unit and continue it's path. The carry-all also nicely slows down before the pickup/drop off point, and then picks up/drops off the unit.

Here is a short in-game video, demonstrating a devastator on the move from 1 side to the other.

Right now, there is 1 little bug related to the carry-all, and that's at the drop off. The unit appears to flash shortly on it's old position for some reason. I need to track that and fix it. After that, I'll fix 1 bug related to scrolling, and re-build the input handling code(In a seperate class).

After that, I'm going to add in weapons.
