Add TravisCI Support, change README to markdown

Rather than testing the Ant build under multiple JDKs, I've arbitrarily
decided to test it only under openjdk7.  This keeps us to 4 builds
rather than 6 before the build is reported as green which should be a
bit quicker.

ant builds copy everything in the pwd into ant_build and then try to
build all of the java files copied, including those of the dependencies
which are built separately.  This does not end well.
