Made all movements in print leveling try to use the speeds out of manual controls.
Probe the 3rd point in 2 point probing so we can set up the correct level equation.
Put in a getting third point page.
Turned some bools into enums for clarity
Broke some of the print leveling wizard into separate files.
Started work on a new 2 point probe (actually an n point switch -> bed position maper).
