[TYPO3-core] RFC: #11368: ENABLE_INSTALL_TOOL file should be ignored if older than one hour

The file is not removed if it has a content "KEEP_FILE".

Not needed and not recommended, as it is file-system specific.

See above. You probably just missed that.

PS: I would recommend setting displayErrors to 2 which triggers errors 
only if the devIPmask matches...
