resources: Add verifiable upstream for various jquery plugins

* jStorage: Plain v0.4.12 release.

* throttle-debounce: Plain v1.1 release.

* jquery.form:
  Plain release. (But they don't have a git tag for it).

* jquery.fullscreen:
  This was a pre-release committed in 3fe5f92a26f02 to fix
  a bug in IE11. We modified the header to indiciate which
  unreleased hash it came from upstream. Shortly after that,
  upstream released it proper (only the header was different).

* hoverIntent:
  I accidentally modified this file in 2011 with 85d5e617d77a1f.
  That (insignificant) change is now reverted.
