[TYPO3-v4] Remove misc/phpheck/

[Sebastian Michaelsen]

For those who don't know this script, try it out:

* Go to misc/phpcheck/incfile.inc
* Comment out the die on top of the file
* Open http://yourt3installation.org/misc/phpcheck/

You'll see a page which prints out some Environment variables and values 
and phpinfo();

It says that you should save it as HTML and send it to Kasper.

Obviously this is from the early days of TYPO3. The Install tool 
provides this functionality far better and I guess Kasper does not want 
to receive any mails regarding this anymore.

So, I'd go for just throwing it out.

Kind regards,
Sebastian
