Differentiate between caption and hint for branch button. Also, just launch Tortoise when clicking on sync status. check-in: b4108802da user: tinus tags: trunk

Also keep current branch and workdir status cached. check-in: 8f789ae9fc user: tinus tags: trunk
10:28
Added buttons for branches and for sync info, but their actions' update method has nefarious side effects (the drop-down button loses its caption and its drop-down arrow). Added convenience functions to get the current file or project's repo info. check-in: a9f098e96c user: tinus tags: trunk
