Balanced The Game

There are changes to everything to balance the game more and I don't
have a good changelog, unfortunately.

Major Changes:
Waves became a lot harder and spawns became faster.
Specific buffs here and there for certain squirrels.
Wave rewards were nerfed.
Wild Squirrels were slowed down.
You can only place one resource tower. ******REMOVING IT IS A PERMANENT
DECISION!!!!******
Changed the Wave Display to be on the TOP LEFT corner.
Changed the Error Messages to be on the BOTTOM LEFT corner.
