Add "show only related" option for Locations

[mertkaraoglu]

Problem description

Currently, the locations widget has the option to only show a certain branch (i.e. alt-click on a branch hides all other in the tree). It would be highly beneficial if there was an option "show only related" which hides every other brach in the tree-view but the selected branch, its parent branch (where it has branched off from) and their remotes (or if clicked on the remnote, then, their locals).

Preferred solution

This can be done by having the option displated in the context menu opened with a right-click inside the Locations widget.

Alternatives

May be one alternative is to leaving out the parent branch in this context and only showing the current branches remote and local.

Hey @mertkaraoglu,

Great idea - I'll have a think about this more and see what I can do!
