TYPO3 / TypoScript: This snippet adds a class (eg. class="page-pagetitle") to the body tag of a TYPO3 page. The page title is dynamically pulled from the page properties, all non-word characters are removed and the title is transformed to lower case letters only.
TYPO3, Extbase: Instead of using the <f:format.html> ViewHelper to parse a RTE database field with the usual TypoScript lib, use it inside a controller. This is useful for instance if we pass something back as JSON. (this not special - it's actually borrowed from the original ViewHelper - I just wanted to keep it around in case I need it again)
