-----------
adding back button evaluation so you can do 1/60, 90*0.1 etc as well as dimension conversion 1km-10cm+4ft
Note...
- Python3.1 you don't need to add the .0 for divisions anymore (was esp annoying for button eval)
- Simple dimension input, imperial mi/yd/ft/in, metric km/m/cm/mm, Later could display these values and have a pref for scene scale, atm it assumes 1BU == 1m.
