2.5

Made 'select-tweak-grab' work in 3d window, fcurve and nodes.
For nodes it works with both left/right, the others follow
user preset for select.

Tweak is a WM event, which also follows user preset for 
tablet-style tweaks (release = apply).

You enable tweak events with an operator WM_OT_tweak_gesture.
Keymap entries can assign to left/middle/right button or to
action/select button tweaks.
