* split Screenshot upload & management into separate endpoints
* move shared functions to manager classes
* cleanup javascript
* move test for config screenshot min size to cfg class
* reworked upload process to be more user-friendly
* handle bricks that consist mostly of localized text separately
* added handle to display errors, when adding CommunityContent on the page they originated from
* editing after upload
* reputation gain for approved uploads
* moderator interface (albeit a bit wonky)
I still do not speak French, Spanish or Russian, so translations are
appreciated
