Also:
* Refactored tests
* Added tests for ve.dm.Transaction.newFromInsertion
* Added tests for ve.dm.Transaction.newFromRemoval
* Fixed problems with ve.dm.Transaction.newFromInsertion
* Added ve.dm.Node.canBeMergedWith which is partially a port of ve.Node.getCommonAncestorPaths merged with canMerge from within ve.dm.DocumentNode.prepareRemoval from the old ve codebase

The 'insert' and 'remove' operations weren't implemented in the
transaction processor and were a holdover from the old DM
implementation.
Also migrated the tests, especially those that asserted that consecutive
insert/remove operations were combined (this is no longer the case now
that they are replace operations)

* Also removed beforeSplice and afterSplice in favor of just plain splice which is the same as afterSplice used to be - beforeSplice was never used and it was making things more complex looking than needed

It's not being used at all, and it's broken because
this.lengthDifference is set to zero regardless of what length
difference the operations passed into the constructor might cause
