[TYPO3-core] RFC: Fix #7657: Add hook to $TSFE->contentStrReplace()

[Michael Stucki]

Thanks Steffen and Olly!

I have committed this change no, the revision is 3338.

Changeset: http://code.typo3.org/v4/changeset/3338

Here's one more little exmple for using this hook:
Conditional CSS is getting more and more difficult to maintain. Imagine how
easy it would be if you could simply wrap your body tag with a class which
defines the browser which is used:

td { border: 1px solid red; }
.ie7 td { border: 1px solid blue; }

Solution: Use this hook and replace a marker inside the body tag with the
output of t3lib_div::getIndpEnv('HTTP_USER_AGENT').

Enjoy! :-)
