Make note to try emacs-eclim for PHP support

I discovered it by accident looking up something else.

Being dependent on something as large and clumsy as Eclipse might get
old, but on the other hand, having auto-complete and jump-to-def in PHP
would be really nice, if it works.
Use smartparens in text-modes instead of autopair

On the whole, I think it's more reliable than autopair now, so I'll
probably be moving over to it.

Not sure if it'll handle Python's TQS well... I guess we'll see.
Use emmet and closing tag completion in xml-mode
