Xaa: antialiasing function

There are probably still some bugs, because I didn't test all the possible parameter combinations. Please report any problems.

It also includes a port of the edi_rpow2 function, but there is already a function with that name in VapourSynth (completely different inside). Not sure what to do with that.

Awesome work as always!

I tried the example for santiag:
xaa.xaa(clip, mode="di2 znedi3", mask=0, chroma=1)
result is :
xaa.py", line 729, in xaa
aa_pass = int(mode=[0])
TypeError: 'mode' is an invalid keyword argument for int()

Mrdaa also doesn't work :)

Thanks for testing. It's fixed in v2, along with some other errors.
