Consistent naming for Operation/Ability

[andrewzhurov]

In the UCAN spec a verb to call on a resource is called Ability, whereas in invocation spec it's denoted as Operation. Would it be more consistent to use the same name across specs? Consistency would spare some cognitive effort to keep in mind Operation = Ability, make learning the specs a bit easier, as "ah, that's a familiar concept" will click faster.
