Refactor UserInfo

[fletchowns]

From evol262:

AwfulClient.userinfo is a huge mess of shit that should be in UserInfo, which should inherit from AwfulClient and set all that in init. AwfulClient.userinfo can return UserInfo(userid) which sets it all

Everything you're doing with "contacts_elem.find('dt'..." could (and arguably should, so it's testable) be done from a private helper method that takes **kwargs if necessary to pass extra shit in. How many times is "elem.find(...).get_text()" in there?

Same for "[tag.extract() for tag in soup.findAll(...)]"

And in __process_paginators
