[request-tracker-maintainers] Bug#821833: request-tracker4: should not set WebBaseURL explicitly

[Dominic Hargreaves]

Package: request-tracker4
Version: 4.2.12-6
Severity: normal

As discussed on the #rt IRC channel several months ago, the Debian packages
set WebBaseURL from debconf, when upstream says that this should nearly
never be set directly.

I suspect that this isn't strictly required, but may be wise purely so
that when people ask for help the configuration is more what people
expect.

There was a related problem where the user was confused about trailing
slashes (RT complains but debconf should have complained instead).
