Started the waypoint system, first by building a shell
Point systems compile, but they need testing
Lack of automatic screen flipping is a pet peeve
Created the TestSystems scene, empty right now
Tested point systems, and fixed bugs
Removed public access of WaypointManager's utilities
Working on paths, finished auto deletion when a path's end point is deleted
Finished WaypointManager, created KeyboardState

The scene-based controls for WaypointManager can be copied into some
editor system later. KeyboardState, while I'm not too happy about it, is
here. It'll act as SDL_GetKeyState()'s replacement, and can be adapted
into a text input system later.
