Integrate post processing for links handled by typoLink
Currently there's no possibility to execute a post processing on each link. There's a way to do this in t3lib_tstemplate->linkData (e.g. RealURL uses this), but it's only for internal links to pages. For links to an external resource there's no way to handle this in a general context with typoLink.
The feature request is to implement "$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['typoLink_PostProc']".
