* refactor status media handling into separate functions, handle case of changed metadata
* update fetchRemoteAccount{Avatar,Header} to use new refactored {load,update}Attachment() functions
* whoops, nearly marked avatars as headers :')
* reformatting to improve legibility
* small formatting changes, rewrite fetchRemoteMedia to use separate funcs + use mutex lock correctly
* move url parsing before acquiring mutex locks
* use wrapped mutexes to allow safe unlocking. (previously i did a fucky and passed mutex by value...)
* remove unused code
* use consistent map keying for dereferencing headers/avatars
