Add 'browse all' and 'ask us to add' to authority search.

This is the template used when the user is searching for a public body
specifically to make a request to.
Show highlights and correction regardless of search type.

Contributes to #1118.
Don't show link for browsing bodies

The context here is that bodies have merely been included in the search
- it hasn't been explicitly restricted to bodies. So the links don't
really make sense.
Don't show sorting links when there are no results.
Show 'browse all' and 'ask us to add' one for authority only search.

This is for the case where there are no results and the user was
explicitly searching for authorities.
Switch .tx/config to refer to transifex.com instead of transifex.net

The transifex-client version 0.9.1 rejects the transifex.net URL,
with the following error:

    CertificateError: hostname 'www.transifex.net' doesn't match
    either of '*.transifex.com', 'transifex.com'

... so update it to transifex.com.
