#35 Suggested Pagination doc

[Michael J. Pedersen]

I suggest the attached new page of documentation on pagination.

Arguably, it's not necessary, since paginate() in decorators.py has a good docstring, but:

• a usage sample still helps

• currently, searching on paginate in the TG2 docs only brings up the webhelpers.paginate page, which is terribly confusing - it implies you need to go figure out the raw Pylons stuff on your own.
