allow find grained testing with server start/stop

I wish to be able to configure hudson runs that smoke test using a given group or groups of tests. When testing interactively, the process is:

(start desired server in another shell)
cd testsuite; ./build.sh -Dtest=foo test
(stop server)

However, I'd like to be able to do this as a single command, so it can be easily automated in hudson runs.

Suggested approach:

testsuite/build.xml:

<target name="test-with-server" if="server" depends="init"
description="Execute a singe test with specified server config startup/shutdown">
<server:start name="${server}"/>
<antcall target="test" inheritRefs="true"/>
<server:stop name="${server}"/>
</target>

and likewise for one-test.

Whilst this change is minimal, making it work would also require fixing server:start so it does not incorrectly barf when passed an arg of "default":

java.lang.IllegalArgumentException: There is no server named: default
