Blender Git Loki

Combined BlenderPro Brazil workshop fix + Patch 29302

Loopcut operator now has two extra features:
- Pad plus/minus allows to change amount of cuts
- typing numerical input works too.

(Number input max is set to 32 now. The code doesn't allow editing
values or backspace it away, nor does it show in header...)

Thanks & congrats Daniel Macedo for his first patch! :)
