[TYPO3-core] Patch: Hook in show_item.php

[René Fritz]

This is a CVS patch request

... I just realized that I accidently comitted the patch already. :-/
Therefore the attached file is not a diff but the changed function as 
textfile, sorry.


Type: feature

description:
The patch introduce a hook in show_item.php and make it possible to render own 
info output for records or files which is normally triggered by the (i) icon 
and diplayed in a popup window.

It is implemented in a way that the class itself decide if it wants to output 
the info. Therefore it is possible to register a rendering class for a single 
table or even a single record.
