[Bf-funboard] little improvement: align view3d.localview to object's local axis

[Seweryn Niemiec]

Hi

Sometimes one wants to fine tune mesh of object already positioned (and 
rotated) in the scene. It would be much more comfortable to work with 
mesh in edit mode if keys 1/3/7 on numpad align view to front/side/top 
according to object's local axis. So it's not about transform axis, 
which already can be changed, but about view axis and more about its 
rotation than location and scale. Local View mode would be perfect place 
for such functionality, as itself name suggests it.

In object mode numpad shift-1/3/7 provide such functionality, but it 
doesn't work in edit mode (view is aligned do selected vertex/edge/face 
axis).

Expected behavior:

When in local view mode, numpad 1/3/7 gives front/side/top view of 
object no matter how object is rotated on the scene.

I can see following implementations:

- temporarily cancel all object transformations when entering local view 
mode (perfect solution but only for one object selected when entering 
local view)
- temporarily cancel objects rotation transformation when entering local 
view mode
- align view axis rotation to last selected object's axis rotation
- add axis selection to view properties panel
