Permissions fix on mysql data directory to avoid errors during `vagrant up`
Ignore entire wp-content directory in wordpress-default
Added support for configuring MySQL through the my.cnf file. Any changes made while vagrant is up should be properly detected via Watchr and recopied over to the MySQL dir & restarted. There was some weird issues with trying to symlink this my.cnf file so cp worked just fine. Also added a init.sql script that will create a user for external purposes like Sequel Pro and PHPStorm 6 without SSH - more details on this soon. The actual MySQL query could probably be perfected so it doesn't cause an error when the user already exists ( on 1+n boots )
