Transform: default to user-defined orientation

Previously we tried this but reverted (see 64d40c82c324)
because there wasn't a predictable set of keys to use global-space.

Now the keys are swapped:

- 'GX' always transforms in the user defined orientation.
- 'GXX' always transforms in global space.

As before 'GXXX' cycles back to disabling constraints.

This does have a down side that GXX won't be used for local-space
when the user has global space set.
Also, when global is the user-orientation, pressing GX and GXX
does the same thing.

Note: examples here use GX but could be any transform-mode/axis.
