I suppose this was a good idea for HPC, as it assumed that source code
annotations coming from a source file could only talk about the same
source file (by how Mix files are saved).

I don't see a reason why cost-centres or source annotations would want
that kind of behaviour. I introduced a flag for toggling the behaviour
per tickish.

(plus some minor refactoring, as well as making sure that the same check
applies to binary tick boxes, where they had apparently been forgotten.)
