Subject: [PATCH] ant fasttest: for when you just can't wait

Cuts major corners for speed. Tests start in SECONDS instead of minutes.
SIGNIFICANT limitations (see below!)

Usage: ant fasttest -Dsingle=TestClass

The idea is that you do a regular "ant test -Dsingle=TestClass" (or "ant committests")
FIRST, then do "ant fasttest -Dsingle=TestClass" for all subsequent runs until
satisfied.

LIMITATIONS:

-REQUIRES that a full test build has already been done (using one of the
 test targets like committests, or a manual "ant test.compile").
-Java only
-Single test class only
-No contracts
-Build jars in dist/ not updated, only classes in build/
-Version number output at runtime may be incorrect
