Moved URLs into nb_api.NationBuilderApi.

They have been moved from __init__ because they all rely on the nation
slug, which is only set once the NationBuilderApi has been
instantiated. They are not in the subclasses, as some of them are used
by different APIs (sort of).
Added emacs and library gitignore patterns

Added tag_person() method, and renamed Tags class to NBTags.
