Have a way for the installer to set all relevant debug flags by default
Certainly useful on like the CLI installer
So in LocalSettings.php, we get near the top:
error_reporting(E_ALL);
ini_set("display_errors", 1);

error_reporting(E_ALL | E_STRICT);
And at the bottom...
$wgShowExceptionDetails = true;
$wgShowSQLErrors = true;
$wgDebugDumpSql = true;
$wgDebugLogFile = ''; Enter a path to use this
