Startup fixes:
* Check that Hg works before open-or-stat, and only open-or-stat if tests successful
* Make multichoicedialog for open always reopen with the same choice as last time (vital when an open action is aborted and user has to enter details again)
* Offer to create full path to target dir for clone if parent doesn't exist
