Add function to access most Laravel functions

[glennjacobs]

I added the function twig_l to the functions list. This enables the use of most functions which accept strings as parameters etc.

Hopefully you'll think it's a good addition :-)

Cheers

I forgot to include an example! Here you go...

{{ l('Form::label','password_confirmation|Confirm Password') }}

I've done this a better way now, will resubmit when implemented.
