Added the doctrine function, changed of the PECL install... the not_if
command doesn't seem to be working with us. Using ignore_failure for the
time being now. Used template to write the databases.yml file and also
changed the apache2 site conf to point to the installation in vagrant
home. Finally, added the symlink for symfony and ran the doctrine
commands to drop the database and so on.
Corrected some mistakes in the web.conf templates.
Adding the databases.yml.erb template.
Changed the settings to host instead of local for postgres.
Ignore .vagrant and sublime project settings.
