Many improvements in the pyramids system, UI and schemes

* MNG/Webp animations support

* Fix GIF loading

* Hashmarks searching

* Hashmarks schema validation

* Async hashmarks broadcast message JSON validation in the
  pubsub service

* searchAllByMetadata() now async

* Use a rotating cube in the status bar as a P2P connection
  quality indicator (rather than a boring label).
  The more peers you have, the faster the cube rotates.

* New animation: rotating-cube-redflash-140-6fps.gif

* Mediaplayer UI fixes

* Add a "Reload" button in the DAG viewer when
  viewing a node from an IPNS path

* ipfs.dag.EvolvingDAG: support DAG rewinding

* The UI should now be more uniform across platforms,
  we use the Fusion style everywhere

* Can now filter for pubsub events in the eventlog watcher

* Improve the pyramids system, adding a type of pyramid
  that works on an EDAG (Evolving DAG). The image gallery
  is a first simple example of that.

* The dweb: scheme handler is now 'native' (derives from
  NativeIPFSSchemeHandler and is fully async) which means
  it does not use the go-ipfs http gw (there's no scheme
  left which uses the gateway now).

* The NativeIPFSSchemeHandler, when faced with an unknown
  dag type, will redirect to 'index.html' if present at the
  dag root (time will tell if it's a good idea ..)

* Minor changes in the DAG viewer UI (use a  single tool button)

revbump to 0.4.18
