Allow closing branches without having to update to them.
Attached is patch showing an initial draft implementation.
Use case: Often I want to close a branch, but in large repos there can be substantial working directory updates that occur when updating to it. So update time taken to and and from branch together with external IDE observing file changes, makes the task far more painful than it should be.
Feature Request: Allow right clicking on a revision and selecting "Close Branch". If revision is not a head and has children with the same branch name warn the user before closing branch.
