Added a build target "unittest-no-junit-report" to run unit tests and
not create a junit report, but instead to show test run results in
the ant output stream. Modified .travis.yml to use
unittest-no-junit-report instead of unittest, and to change directory
to core before doing the build and unittest.
Modified application startup to set the base translator the same way the
guice startup does - if the locale is set to 'xx' then the base translator
is the debug translator, otherwise the base translator is ResourceBundleTranslator.
You can set the locale by passing '-Duser.language=xx' to the jvm when starting up.
This fixes github issue #17.
