Version Changes Restore (ish) and Verb Fixup from Issue #444

#444 on the verb side, still in a bit of a pickle with the versioning within Statements.  As you can see, we have both 1.0.0 requirements and 1.0.1 requirements.  I think updating all of these to 1.0.3 is premature, but can we really leave them half and half?  I propose updating all to 1.0.1.  Big question - does this break any actual implementations, or was this something the LRS providers didn't follow because it seemed illogical?
Are you implying here that different language implementations should use different IRIs to represent the same meaning? The point of the IRI and the language map is so that the same IRI can be used in all languages because they all describe the same event. 

This does have the implication that if somebody coins an IRI in an implementer's non-native language (or even alphabet) that has no impact on whether or not the implementer should use that IRI. We might want to consider saying that for verbs, activity types, extension and attachment usages (i.e. all the shared IRIs) the human readable part should be in English; I'm not sure how I feel about that.
