[TYPO3] Removing the meta "generator" from header

I know this, and I agree with you: it is absolutely reasonable that the 
pages report that they have been built through TYPO3.
As you may see, I did not complain about this, and agree with the fact 
that the header of the pages includes, for instance, the following note:

<!-- 
	This website is powered by TYPO3 - inspiring people to share!
(...)

This is good.

It is not my will not to have respect for TYPO3, which is a software I 
use and like a lot. I'm sorry if I gave this impression to you.

What I don't like, and would like to avoid, is to show the VERSION of 
TYPO3 through which the pages were built, basically for security reasons: 
imagine that I have used a version of TYPO3 that later is discovered to 
be buggy about security, and I haven't had time to update yet. If the 
code of the pages shows the version of the software, this could be an 
hint for malicious people trying to force my system: they might be aware 
that my web server is using a buggy software and trying to break it.
Up to now, TYPO3 has looked solid as a rock to me, but who knows what 
might happen in the future? Bugs happen.
For instance, I find absolutely reasonable that the administrative login 
page (http://mysite.org/typo3/) does not display the version of TYPO3 in 
use, for the very same reason.
Best regards
