Subject: Long overdue rehaul of presentation compiler te...

Long overdue rehaul of presentation compiler tests. Added support for
options file, and switched simple-tests to use the STARR library on the
test classpath.

Put any options you need passed to the presentation compiler in a file
with the same name as the test, ending in '.opts'. Currently it's used
to set the -bootclasspath for simple-tests. Check the contents of
simple-tests.opts for all the options.

IMPORTANT: when committing a new STARR, you need to check this test.
Most likely, you *will* break it otherwise.
