Catrope 1176bf9677 Move .commit()/.rollback() from TransactionProcessor to Document
Previously these were static functions in TransactionProcessor
which instantiated a TP called .process() on it. These are now
methods of ve.dm.Document.

Also moved the emission of the 'transact' event on the document from
TransactionProcessor to Document itself, and moved the tests asserting
double application is protected against from TP to Document (because
the corresponding code moved as well).
