2.1.0 - IPFS improvements

• pubsub:// had some bugs when receiving messages. This has now been fixed, but you'll likely want to clear your ipfs/config file in your data folder. This should also give better compatibility with agregore-mobile
• ipld:// now supports loading IPLD Schemas in path segments to apply onto data as it's being loaded. This can let you apply more human-readable "lenses" over top of compact IPLD representations.
• ipld:// now also supports the IPLD Patch spec. With this you can apply "patch sets" over an IPLD DAG along with respecting any schemas placed in the URL. With this you can have determenistic updates to datasets with minimal code.
• You can check out how the new URLs look in the js-ipld-url-resolve unit tests
