generic x-scheme-handler required

Working with telnet:// and ssh:// handlers requires support in xdg-open to support these. Chrome by default uses xdg-open to open these URIs and with Trusty these are not supported. Here's a patch that works for (it might not be generic enough, though). Also wondering if the scheme RE can actually contain a + as in here ^[a-zA-Z+\.\-]+: or if this would be a better RE ^[a-zA-Z\.\-]+://

Might be that this has to be fixed upstream...

Thanks,
