-------------
- mainly enhancements in test suite
1. executable flag on run_test
2. added base class for testing views
3. support for rednose in tests (rednose seems not compatible with multiprocess plugin)
4. Test* classes not imported in utils.__init__ (forced test requirements even when running gap project)
5. test requirements ignored by gip (not usefull on production)
- fixed link in changelog
- extended Route class which can better handle ending slash
