Doc - Adding new protocols missing guacamole-client

[David Haukeness]

Hello,
    I'm working through the documentation and have worked through the 
"adding new protocols" section that covers guacd, however there's no 
guidance on what/where needs to be modified on guacamole-client to get 
the new protocols to show up in the "Add new connection" screen, or demo 
the connection.
    Is there a resource available that explains this part somewhere? 
alternatively is there someone willing to offer guidance, and i'm 
willing to write it up and PR the manual?

Thanks,
    David
