Updated nuspec files with release notes for 0.4.0.
Updated version number to 0.4.0 for release.
Updated version number to 0.4.1 for development.
Adding new test project for integration tests.
Integration test for unsolicited signin.
Test on unsolicited SigIn

- Works, but timing issues should be improved.
- Should fix test playlist to be able to run unit tests separately.
Moved Integrationtests to own solution.
- When running the Selenium tests, it is better to have them in a separate solution. That makes it possible to start the main solution in the debugger and then run the tests separately.
Fixed timeout for SignInTests.
- When the test fails, we don't want it to wait 30 seconds (or even 5) hoping that an Ajax request will magically fix the data. Fail is fail.
