Merge pull request #1311 from wsargent/patch-1

Fix dead link to requirejs "Next" page.
Fixed a regression that resulted in the action body being executed on the iteratee execution context, and not the users:

https://github.com/playframework/Play20/commit/7e58680e44890b5d0a292d0f98fcc6bf936e3c4d#commitcomment-3584037
Fix in relation to issue #1332. It appears as though connection failures were not permitting an iteratee to be completed. This caused a particular issue with respect to chunked replies.
 #1329 Improved spec compliance with etags

- RFC2616 requires that if an etag is given with the If-None-Match
  header, but doesn't match, then the If-Modified-Since header must be
  ignored.
- This was causing issues specifically when rolling back a deployment.
- Also moved the AssetsSpec out of the integrationtest project and into
  play-integration-test, to make it simpler.
