Autoupdate _mj.cgi

[p0i5k]

Update _mj.cgi after update majestic from web interface. Options:

1. Add key --parameters (-p -P) to majestic for getting all supported parameters
2. Parse majestic.yaml

I'd rather get rid of _mj.cgi at all, if only majestic had a key to generate such an output on its own.
