* the great unfuckening of user and displayName
* `login` is purely used as login with AUTH_MODE_SELF
* `email` may now also be used to log in (if the system knows it)
* `username` is purely used for display around the site, and lookups from web context
* both must exist because of external logins
a) that may be not unique
b) you may not want to share with the rest of the world
* todo: implement rename ( because of b) )
* append a filemtime timestamp to js/css files to work around browser caching after update
* shuffle script handling around a bit
* also user pages cant have community content
* also fix breadcrumbs on items page
* aproving a screenshot now flags the corresponding db entry as having a screenshot
* deleting & moving screenshots works equivalent
* instancing a new TypeClass without parameters no longer grabs everything from the corresponding tables ( pass a "[true]" to retain this behaviour)
* retroactively flag db entries for having screenshots
* fixed a typo
