New online cache manifest checker/validator

[Albert Wiersch]

The online validator at http://www.OnlineWebCheck.com/ can now check cache manifest files.

Here is more information about HTML5 cache manifests:
http://en.wikipedia.org/wiki/Cache_manifest

To check a cache manifest, specify a URL that is of type text/cache-manifest, or use the 'Advanced Interface' to enter the manifest file into the text box and select the 'Snippet is cache manifest' radio button, then click the 'Check Above Document or Snippet' button.

Please note that as of July 23rd, 2014, this is considered a BETA feature.
