Add support for xUnit-format XML output by utilising the 'xmlrunner'
package. This feature is optional, and is disabled by default.

Resolves issue #123.

oft: Move profiler setup/teardown to function

Profiler setup/teardown was done "in-situ". This was inconsistent
with the general design of 'oft'. Fix this, by moving these
operations to a seperate file.

In addition, add a '--profile-file' parameter, so that the output
file can be changed if necessary.

oft: Enclose 'xmlrunner' import in try-except

If the 'xmlrunner' package cannot be imported, an exception is
thrown. Unhandled, the datapath will not shut down causing the
program to hang. Ensure the datapath is killed before re-raising
the exception.
