Title: Remove Compiler fallback option.

I inadvertently removed my `app/resources/tmp/cache/templates` folder
and PHP was unable to write the compiled templates in it.
Instead of throwing an exception/error, the Compiler returned the
unparsed file without telling anyone what was happening (no error, no
logs).

With `$foo; ?>` appearing on the page I quickly saw that there was a
problem but if I had `short_tags` turned on, the unescaped variable
would have been printed (hello XSS!) and I would never have noticed it.

This behavior is dangerous.
