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 

I don't feel that anything should be limited to PHP. Everything works well with every files, why limiting all these great vim features to PHP? The first example that come to my mind: set numbers

Still TODO: you have 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.
