Added daemon-test
Add support for generic external tests or shell scripts; Add daemon test; Removenon-generic ezexample code (now supported in a nicer, generic way)
Add empty-set test (getting SEGV on bad builds so good to cover this)
Append test and . to PATH so shell scripts are found more easily
PATH fixes (so travis is ok with daemon-test)
Make sure we find vw first
Still failing in travis, but now with status 1. Make sure daemon is ready.
Doesn't need bash - runs fine (and faster) under sh
Fix some quotes and error case
Add -x to help figure out why travis isn't happy. Should fail.
The diff is failing. Why? Could it be 'nc'?  Switch to 'netcat'.
Check for pkill and netcat existence in PATH first
Still failing travis; enable -x again, add more waits on start-daemon and make model smaller
Minor fixes, remove -x; still no idea why it fails travis.
Could it be the port number?
Move empty-set.stderr to its right place; switch order of last two tests
Moved test/train-sets/empty-set.stderr to 'ref/'
