Rename Version names

[iknite]

Proposal:|

ActualVersion -> InsertionVersion (This is the version on the time of writing the event)
CurrentVersion -> TreeVersion (This is the version on the time of the query)
QueryVersion -> QueryVersion (This is the version asked for)

Thoughts?

My proposal:

ActualVersion -> EventIndex
CurrentVerrsion -> ProofIndex
QueryVersion -> QueryIndex

Changing Version LGTM to Index, as long as we change every reference of version (and not only this 3 variables)

Using "object names" for temporality (when is stored, and consulted) seems more confusing to me, that's why I've been proposing Insertion. (and this doubt also applies to my TreeVersion proposal)

Just my 2 cents.
