[TYPO3-v4] Upgrade wizards needed

[Steffen Gebert]

Hey guys,

does anybody have a few minute for creating the following upgrade wizards  
for the Install Tool?

* Check for $TYPO3_CONF_VARS[BE][compressionLevel] active and warn user to  
include the lines from misc/advanced.htaccess
* Check for having EXT:t3skin installed and warn user to install it or  
another 4.4 compatible skin

Both wizards are sufficient, if they simply warn the user that it will  
result in a broken backend otherwise.

Thanks in adnance! Would be great, if sb. could do this.

Steffen
