Title: deprecated the token parser broker sub-system

This is the first of a series of PRs where I want to deprecate some features that made sense at some point but do not anymore or features that are barely used. Deprecated features will still work in all versions of Twig 1.x but they will be removed in Twig 2.0.

This first one should not be controversial. The token parser broker was added at a time where functions in Twig were not available. Nowadays, creating a new tag is so rare that I cannot see any usage for the broker system.

As far as I know, nobody uses the broker system anyway (this feature is not even documented), except [Zwig](https://github.com/arnaud-lb/Zwig). And Zwig should probably create functions instead of tags for ZF helpers anyways.
