Add page=None parameter to all views. Information from page argument (which is soc.logic.site.page.Page object) is going to be used later in views code and for some context values. Fix some indentions in __doc__ strings. Add proper __doc__ string for all() function in sponsor/list.py module. Patch by: Pawel Solyga Review by: to-be-reviewed
