Add .numberFormat function to stdWrap
When handling prices or other special formated Numbers in TypoScript there's no reasonable way to format it properly. When there's a price like 0.8 in your Database you can't transform it to 0,80 easily.
There's already an extension adding this functionality by XCLASSing (am_stdwrap_number_format) and requests for such a feature (http://www.typo3.net/forum/list/list_post//89143/ [german]), so I think a general interest for this functionality is given.
