Added a main menu, an options menu, and a level editor.
Current level editor controls:
Up and down arrow select tile type. (check upper right cornor to see selection)
Right and left arrows pan camera.
Left click to add/change tile. (or select something no the menu)
Right click to bring up menu.
And both ingame and in level editor you can use ESC to get to the options menu and then to the main menu.
edit:
realized a bug where if you pan the camera then place a brick, it won't account for the fact that the camera's panned
double edit:
fixed
