Add mode to Reset menu name; optionally with a Preference to choose default mode

Users coming from Atlassian SourceTree are used to Mixed being the default. And, I almost never use hard reset, though others clearly do.

It would be clearer if the reset menu's name included the mode. So instead of "Reset.." it would say "Reset (Hard).."

It would also be convenient to have a preference that changes the mode of the "Reset.." menu. If you did both of these suggestions, the "Reset.." menu name would change based on the selection.
