Ignore marked files

[krzysztofrewak]

@jsawo would like to ignore some files during search. I would add a new method to config file, something like this:

$config = new Config();

return $config->ignoreMarkedFiles()->config();

or:

$config = new Config(
    ignoreMarkedFiles: true,
);

return $config->config();

"Marking" could be implemented as custom declaration in files or some specific docblock.
