gitweb: Make linking to actions requiring JavaScript a feature

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.
