Added NUnit.Runners, which include nunit-console allowing automatic bisects for broken tests
Fixed StaticScenery tests: mock wan't actually used.
Added file generated by nunit-console into the .gitignore list
Commented disabled tests (we just waste time updating them)
Added extra plugin verification for WebTests.

Now if a plug-in is expected but not present, the test will fail - most
likely the plug-in was never built.
Added KeyframeAnimation to all WebTests since client uses it
Added fallback to the non-ServiceBus mechanisms when the last fails to load
Removed Motion plug-in from one of the servers in 2-server-test
Merge branch 'fix-tests' into develop
