fixed branch-name (5-3 -> 5-4)

Added ability to add and remove the forked from/to relatioinship
between existing repos.

I've moved the instruction in question to the the 
'Configure GitLab DB settings'. Can't change permission to a file that doesn't already exist 

This includes standard markdown as well as GitLab extended markdown as well as references to documents used.

Recompiling assets on the update is needed or main menu appearance may not load properly. This has been mentioned on issues #3722 and #3978.

The command has been tested several by users on those issues and by myself.

Thanks for your time and attention.

Fix spelling error and make sure you never log in as git user so you never have to logout to run sudo.

s 3599: Add snippets_enabled flag to projects for API

Replace missing comma

The API docs incorrectly referenced a few attributes associated with users. The 'blocked' attribute has been replaced with 'state'. Also, 'dark_scheme' seems to no longer be available in the User model so it should be removed from the exposed attributes in the API User entity.

Add color scheme ID to API User entity
