Here it is.  I am a bit ambiguous about *naming* of this feature (and
whether it should be overridable), that's why it is marked as RFC.

Also the subject of this commit could have been better, I think...

Let gitweb turn some links (like 'blame' links) into linking to
actions which require JavaScript (like 'blame_incremental' action)
only if 'javascript-actions' feature is enabled.

This means that links to such actions would be present only if both
JavaScript is enabled and 'javascript-actions' feature is enabled.
