First step towards restoring / improving subdivide 'beauty'.

Beauty button now is Beauty and Short.

Works as follows

Beauty on: If a face is selected, only subdivide the longest 2 sides
Beauty & Short on: If a face is selected, only subdivide the shortest 2 sides

1 problem atm is when more than 2 sides are equal. Must add code to check for this and disable beauty on that face. Use with caution! :)

Also restoring selection needs to be tweaked here.

Side Note: for most accurate subdividing, use edge mode and select only the edges you wish to cut rather than relying on beauty.
