minor refactoring to tests

wrote a separate integration test for EmployeeFileRepository so that BirthdayServiceIntegrationTest can be converted into a unit test suite.
changed the dependency for Mockito from mockito-all to mockito-core; removed the dependency for Hamcrest as its a dependency of mockito-core.
replaced the actual EmployeeFileRepository instance in the BirthdayServiceIntegrationTest with a mock.
fixed the wrong exception message.
renamed the package using the camelCase; removed the lib directory as the dependencies are handled by Maven.
removed the redundant documents of the (non-portable) formats; added the shebang line in distribute.sh
removed PowerMock version from pom.xml.
