Having keywords in reports be followable

[Hans Zauber <hans@…>]

In reports (such as {8} - Active Tickets, Mine First), milestones are followable, that is, one may click a milestone's name which appears as a link. However, keywords, reporters or owners are not followable.

I have tried patching the code, but it seems like this is needed both in query.py and in report.py (depends on the query type), and in either case putting a link instead of a string is neither elegant nor doing the job, as html sanitizers eat the links.

I think it can't hurt adding this functionality. With very basic help, I am willing to write this functionality myself and send a patch.
