The error handler still puts out messages when suppressed by PHP

[lfkeitel]

If an expression begins with @, PHP will suppress any errors generated by the expression. The error handler provided by oslogger still prints out the errors. The following needs to be added to src/ErrorHandler.php at line 58:

if (error_reporting() === 0) {
    return;
}

Perhaps make an option to always print errors even when suppressed.
