* Added the axis constraints (and fixed a bug) in the newly
added View3D transform menus, and in doing so removed
some duplicated code from toolbox.c
* Cleaned up text labelling
Hint:
Remember to use Title Case for menu labels, and only use
an ellipsis (...) when the menu opens up another new
dialog like a panel or a pupmenu(). The ellipsis indicates
"there is something more to come" and that no action,
mode-change, whatever will be executed immediately.
