[TYPO3-core] RFC: Feature Request #7150: Add pageUnavailable_handling for system problems and maintenance

Hi Jeff,

This is a really great feature, thanks. +1 after reading and testing.

Just one small question. In tslib_fe::checkPageUnavailableHandler() you 
refer to TYPO3_CONF_VARS in two different ways:

$this->TYPO3_CONF_VARS['FE']['pageUnavailable_handling']

and

$GLOBALS['TYPO3_CONF_VARS']['SYS']['devIPmask']

I suppose there's a reason for that, what's the difference?

Cheers
