Title: Tokenize all pseudoclasscolons, rather than just the first.

I found a problem with multiple pseudoclasses:

a ::pseudoclass,
b ::pseudoclass {}

would be minified to:

a ::pseudoclass,
b::pseudoclass {}

Removing the space in the second instance.

Here's a test and patch for the problem.
Thanks.
