This is my current patch against 1.42 b335, it has a
few different logical changes that I probably should
break apart but meh.
* Changed misspellings of apperance as 'Apperanace'
* Moved behavioural configuration settings
(mouse_drag, copy_on_select) out of the appearance
node and into a new behaviour node
* Added an inverse_shift behaviour to change the way
shift is used with select vs drag
See the patched ReadMe.txt.
