[TYPO3] Lower Case "c" Prepended to Bookmarks

This is done to make sure anchors are cerated according to W3C rules.
The tag which is generated during the output will look like this:

<a id="c1234"></a>

W3C rules say: "id" must not start with a number and this is why the "c" is 
added as a prefix.
Don't remember when this has been added to the core, but I do remember there 
was a compatibility version creating anchors the old fashioned way which 
didn't care about any rules.
But since the typolink function is aware of this rule, the links will still 
work as expected and you won't need the comptability setting anyway.
