Add single-axis modes to all visual tools

Browse source 
Make all visual tools only update the most-changed axis whenever shift
is held down. Previously the rotate and scale tools used ctrl for this
and shift for snapping to round values; these have been swapped for
consistency.

Closes #993.

Originally committed to SVN as r4310.
