Static properties dropped on non-static TokenStore classes

TokenStore classes were currently not programmed in accordance with the StyleGuide (mixed static and non-static members).

This release changes that and is potentially backwards breaking.

Bump dependencies

Updated dev dependencies a few times since last release.

Works well with WebEngine

This release mainly contains compatibility enhancements with WebEngine.

The functionality is kept the same, but all post data must be passed into the processAndVerify function, rather than relying on superglobals.

Update Dom namespaces

The PhpGt/Dom repository changed its namespaces to become consistent with the whole of WebEngine. This was a backwards breaking change, which has been fixed in this release.

ArrayTokenStore

The abstract TokenStore class defines how Csrf tokens can be handled. This release includes the ArrayTokenStore mechanism for saving an easily serialisable data structure to your own persistent storage mechanism, such as the session.
