[Bf-committers] More info in the grab status.

[Campbell Barton]

Hi, I have added this on my own PC but was wondering what other people 
thaught of This.

ATM the grab mode only shows Dx: Dy: Dz:

I think it could be Usefull to add a Length, AngleX, AngleY, AngleZ

Dx: 32.233  Dy: 0.0222  Dz: 2.032     Dist: 34.054   Angle X: 30.2  Y: 
11.3  Z: 43.00

The distance would be worked out properly an I have added a formula for 
working out angles.

any comments?
