No space required after WIP identifier

Fixes #2426 

Currently, the WIP: (or any other variation) prefix of a merge request title must include a trailing space for it to be recognized as a work in progress and prevent merging. 
To resolve this, I added an or pattern to the regexp to look for any one of the three possible delimiters ':', ']', or ' '. This way the trailing space isn't required but it still won't mark any titles beginning with wip as work in progress (e.g. "Wipwap").

Support download access by PRIVATE-TOKEN header

Originally opened at !2522.

Currently there is no way to download a raw file without embedding
the token in the URL, which exposes the token in the URL. There
should be an way of sending this information via the header as the
API does.
