Add URL header
Some compatibiliy tweaks

* Prioritize syntax-begin-function over font-lock-beginning-of-syntax-function.
* Check if syntax-propertize-function is bound. It isn't in Emacs 23.
Define mmm-indent-line-function and its default value

* Now html-erb-mode can just set mmm-indent-line-function.
* Easier access to the submode's indent-line-function. No need to hack around.
* mmm-indent-line indents according to the submode at the indentation, which is more
  consistent than previously.
Remove regexp-opt's legacy stuff

Say goodbye to Emacs 19
Merge pull request #22 from purcell/indentation

Merge branch 'indentation'
Move html-js and html-css classes from mmm-erb to mmm-sample

* Overwrite JS and CSS classes that were already there.

* Disregard type and language attributes. The latter is obsolete, the former is
  made optional in HTML5. If we're ever going to dispatch to appropriate submode
  based on attribute value, we can add them back.

* No submode regions for inline code in on* attributes, the added functionality
  is not worth the slowdown (font-lock and indentation are largely unused), and
  such attributes are bad practice anyway.
