FIXED - #7: Session timeout, Login, POST form resubmission fails

- refactor LoginContextServiceImpl.createSavedRequestCookie() based on
https://gist.github.com/dmitrygusev/10573547
- deprecate LoginContextService.saveRequest(String contextPath) as
unnecessary
- enable and implement a few more tests related to saved requests
- add logback as a test dependency and configure it
- change to use jquery provider for tests to get rid of the annoying
javascript errors (htmlunit still complains about use of some selectors)
