I don't see the need in selectively including syntax for modules when I can
just install the modules and include them all. Expanded to include all of the
modules I could that were in the list already and updated. Going to look into
getting a more up to date module list for PHP 5.5+ and expanding further.
This commit introduces a new template file which will be used when
re-generating the syntax from within PHP.
In addition, several less commonly used extensions are turned off to speed up
loading of the php.vim file on start up.
