André Berg 22ba33f575 Disable/re-enable Push, Pull and Rebase buttons depending on selected branch validity.
If "All branches" or "Local branches" is selected, the buttons will be disabled. 
Actions from the context menu continue to work as they implicitly set the target branch
through the identity of the clicked label patch.
Any other branch will re-enable the buttons.
