Edgeslide Mouse Movement Fix

Browse Source 
Edgeslide movement is now controlled by a line drawn between the endpoints of the 2 control rail edges. Edgeslide will
try to pick a control rail pair (will color green ATM) if you don't like the edge it picked, use the mouse wheel up to change it.
have to code mouse wheel down to go other direction still. Just ran out of time ATM and wanted to get this in for movement testing.

movement is in 1% per edge (so 1% out of -1 to 1)
CTRL makes it 10%
SHIFT makes it .1%

Se what you think and give me some feedback on functionality :) Code needs cleanup and comments, so don't crit that too much yet.
