TYPO3 Core

In User Settings we have a button to create or delete the ENABLE_INSTALL_TOOL file. The ENABLE_INSTALL_TOOL file itself is manually deleted on the first access when there's been an hour of inactivity and not immediately deleted when that hour of inactivity occurs. This leads to a User Settings button that doesn't really reflect the current state.

When an hour has passed since the last activity, the User Settings button will still offer the opportunity to delete the ENABLE_INSTALL_TOOL file despite the fact that the Install Tool will not be accessible if you try to browse to it directly.

The solution is to have User Settings update the timestamp on the existing ENABLE_INSTALL_TOOL file or delete the file completely if its more than an hour hold, just like the main Install Tool code.
