Adjustments to continuous grab

- Use an enum for grab modes rather then boolean options.
 -- GHOST_kGrabNormal: continuous grab userpref disabled
 -- GHOST_kGrabWrap: wrap the mouse at the screen bounds *
 -- GHOST_kGrabHide: hide the mouse while grabbing and restore the mouse where it was initially pressed *

GrabWrap is nice for transform and tools where you want some idea where the cursor is, previously I found both restoring the mouse at its original location and restoring at a clamped location was confusing with operators like transform, wrapping is not ideal but IMHO the best of a bad bunch of options.
GrabHide  is for numbuts, where restoring the mouse at the initial location isnt so confusing.
