BPython:

- Added Blender.Run(script) + doc update (forgot to mention in my previous commit).

Trying to fix two mistakes from my previous commit:

- nmesh.transform(): forgot yesterday that affine vectors have 4th component = 0, now updated normals transformation accordingly.

- As Ton pointed, recursive parsing of scripts dirs in search of scripts was a mess.  I simply forgot about the "//" trick and much worse, to protect against worst cases ("/", for example). Now the code uses BLI_convertstringcode to take care of "//", doesn't process if dir = "/" and there are limits:

max depth for traversing subdirs = 4
max dirs in the tree = 30.

I'll work more on this, check more, but these changes were tested and should make the code safer, of course, so I'm committing.  Sorry about the mess, I should take lessons on defensive programming ...
