Renamed service ``doctrine_phpcr_...` tree model and associated stuff

Renamed `doctrine_phpcr_type_tree_model` to `doctrine_phpcr_odm_type_tree_model` because this is an ODM tree browser, and this it is currently the name we should be using the PHPCR tree.

I also wonder, if we do this rename, should it not be `doctrine_phpcr_odm_tree` -- do the `type` and `model` parts of the alias serve any purpose?

This is  a big BC break, so if all is well I will do a PR for all the stuff in cmf-sandbox that affected.
