Add tests for ModuleFileParser
* add ModuleFileParserTest which is BaseContextSensitive since the
ModuleFileParser makes use of Context
* test by creating an xml document and saving it in a Jar with extension
".omod" so its recognized as openmrs module
* also test using the logic-0.2 module file which is under the test
resources
* remove javadocs from ModuleFileParserUnit test as they just clutter
