[TYPO3-project-4-3] FYI: patch for autoloader is in the BT

[Dan Osipov]

I get an error on the main page:
"The autoloader registry does not exist or it is corrupted. Please, go 
to Tools>Manage autoloader registry and update the registry.
If update fails, you can run "typo3/cli_dispatch.phpsh 
lowlevel_autoload" from the command line to update the registry."

But where is Tools->Manage autoloader registry?
