server (blog): cleaning & improvments: - use a constant for themes url - moved RSM related constants to server only constants, and renamed theme STATIC_RSM* - raised the default number of items/comments to 10 - removed references to microblog namespace as it is managed by backend - many little improvments for better readability - dont use dynamic relative paths anymore - replaced use of old formatting syntax (%) by format() - profile name in url is now properly (un)quoted - removed max_items as it was used at the same time as RSM (TODO: check RSM support before using it) - renamed render_* methods using camelCase for consistency - put a limit for rsm_max, to avoid overloading - don't sort items after getting them anymore, as sorting is already done by backend/pubsub according to request - use urllib.urlencode when possible
