Incorrect description for Fallback remote receiver URL

[prl]

The description for MENU>Setup>Tuners>Tuner allocation>Fallback remote receiver URL says:

"Specify the complete URL of the fallback remote receiver including the port number (:8001 by default), e.g. 'IP_second_box:8001'."

It should be more like:

"Specify the complete URL of the fallback remote receiver including the port number (:8001 by default), e.g. 'http://IP_second_box:8001'."

git log -p data/setup.xml says that it was changed to the second text in Jan 2017, but that's not reflected in what's actually in the file.

Fix Bug #585: Incorrect description for Fallback remote receiver URL

Change the description text to give a correct example of the form for the required URL for fallback.

Also gave "Fallback remote receiver URL" a "requires" on config.usage.remote_fallback_enabled so that it only appears when the feature is enabled.
