[Bf-python] module IPO

[Jacques Guignot]

The IPO module has been deeply modified, jms scripts run now, with two 
slight modifications :

    a) The function Recalc is now a member of Curve class, not of IPO 
module, ie the syntax :
    Blender.IPO.Recalc(X)
    has been replaced by the more intuitive :
    X.Recalc()

    b) Bezier points only support global assignment, ie the syntax :
    bz.pt[0] = 4
    bz.pt[1] = 8
    does not run.
    It has been replaced by
    bz.pt = [4,8]

I'll try to get rid of these discrepancies, but, hrrrm..., yes Willian, 
a li'le irc meeting could help :-)

REM : about midi script, I just don't understand. What is it supposed to 
do? No doc, no README...
On 227, it does not crash, but seems to do nothing!
