Parsing of points in -webkit-gradient

[lgriesterer]

In the current version, the parsing of -webkit-gradient fails because of point syntax.
E.g.:

.bug { background: -webkit-gradient(linear, top left, 100% 100%, from(#ddd), to(#aaa)); }

Here is a proposed patch to support points (this pass all the tests):

diff control.py control.py.orig 
44,49d43
< class Point(Value, ParseNode):
<     @property
<     def value(self):
<       return ' '.join(str(e) for e in self.data)
< 
<

Fixed in version 0.8.3
