1. Add CMF bundles and minimal configuration for the CMF

[dbu]

In this branch, we start using Doctrine PHPCR-ODM and the CMF bundles. After switching to this branch, you need to tell composer to install the new dependencies:

composer install

To set up the repository, you need to run the following commands (after making sure you configured a good Doctrine DBAL connection):

php app/console doctrine:database:create
php app/console doctrine:phpcr:init:dbal
php app/console doctrine:phpcr:repository:init

Notes

• I chose jackalope-doctrine-dbal as PHPCR implementation. See the PHPCR website for alternatives.
• The LiipDoctrineCacheBundle is not strictly needed, but will improve performance with jackalope-doctrine-dbal. If you use a different PHPCR implementation, you don't need the LiipDoctrineCacheBundle.
• I did not add any editing tools or fixtures yet. The site is still empty. Content fixtures and then editing will follow later.
