Bug 2524: Adding script to submit test reports to smolder server

This patch adds a target in the t/Makefile and a script in t/smolder_smoke_signal
to submit the results of test runs to a smolder server. It will allow users to submit
their own test results to a central location by running "make submit" from the t/
directory.

Smolder is a web-based application that aggregates and presents the output of
tests. We have an instance running at:
http://arwen.metavore.com:8000/app/public_projects/smoke_reports/1

More information about using smolder for Koha is available at:
http://wiki.koha.org/doku.php?id=en:development:smoke_reports

I intend to have the test suite run each night automatically and the results
sent to the smolder server. This will help us keep track of the current state
of the the code and possibly catch bugs introduced by changes. I encourge others
to submit their own test results if they want, especially if they are on an unusual
platform or are with a non-standard configuration.
