allow prefix matching for actions
This offers some command line convenience, allowing the user only specify an action prefix as long as it can be resolved without ambiguitiy. For example, as of this commit, 'asp up' would then translate to 'asp update', and 'asp d' would be an error (as 'difflog' and 'disk-usage' are both candidates).
