Many changes

Camera logic now contains the next level function...would normally be in
a level settings script but we don't have one.

Included a new "launcher". can be placed anywhere and when the player
hits it, they will be launched in a specified direction.

I also included a basic upgrade system. Pick ups can be placed, and will
choose a color based on their type (later can be changed to sprite.)
Upgrades will persist for multiple levels, and be reset to a default
attack. NOTE: When we change these, updates will need to be made in both
py_pickupSettings and py_globalVariables
