[Bf-python] loose ends in Curve

[Gilbert, Joseph]

Window (or blender area) redraws are used sparingly in the api as they
can be unnecessary. Originally I went hog wild adding window redraws but
I remember willian explaining to me that in a script some of these
'forced redraws' are not necessary and in some cases may slow down the
script with unneeded redraws. Example:
Mesh.addThingy(myThing) internally forces a redraw. You then have a
script that does
For x in range(1000000):
...myMesh.addThingy(x)
Which forces a million redraws of the 3dview area. (if you call
allqueue() it forces a million redraws of every open window) The idea
was to have the Window.Redraw() method to allow script users the
flexibility to redraw on their own:
For x in range(1000000):
...myMesh.addThingy(x)
Window.Redraw()
I guess it depends on how your code will be used and wether or not
forced redrawing is acceptable or if it is better that you put a
@warning in the docs that they need to redraw.
(that's my take on it at least) :)

ah forgot about that, thanks, works.

please commit - i guess that's a fix so can do during the freeze .. at
least 
then there'll be a way for this to work!

dunno (what it is, even).

oh i thought it might be that cu->bevob, but did not have an idea why.
how 
come does it end up with no data? i'm doing ob.link(curveob) and 
scene.link(ob) after every succesful creation.
