Support for arbitrary sized vectors - (was limited by 2-4 previously)

patch http://codereview.appspot.com/5482043
from Andrew Hale

* Text from the submission *

This patch adds the ability to use arbitrary sized vectors from mathutils.
Currently vectors are only of size 2, 3 or 4 since they are generally restricted
to geometric applications. However, we can use arbitrary sized vectors for
efficient calculations and data manipulation.
