Support a bit more than PHP

I moved some line in .vimrc. It's not optimal but at least it will show why you should not have restricted vim to PHP files only :P 

Before this patch, you had to open a PHP file to be able to see the F8 right panel - which is a shame because this panel works very well with all type of file => js, html ... which are quite common in Moodle.

I don't feel that anything should be limited to PHP. Everything works well with every files, why limiting vim to PHP?
