Released v0.7

Bug-fixes and improvements:
* Closes #5
* Closes #1
* Adds Client (beta)
* Added several schemas
* Lighter string representation -> should avoid delays in the analysis
  with plugins that have 'heavy' attributes

Backwards-incompatible changes:
* Context in headers by default
* All schemas include a "@type" argument that is used for autodetection
  in the client

... And possibly many more, this is still <1.0
