* Client now raises an exception on error
* Added conversion to the documentation

* Changed the way modules are imported -> we can now use dotted
  notation (e.g. senpy.plugins.conversion.centroids)
* Refactored ekman2vad's plugin -> generic centroids
* Added some basic tests

Am I a complete moron?

* Docker all the things!
* Make all the things!
* Fixed version.sh

* Added conversion plugins (API might change!)
* Added conversion to the analysis pipeline
* Changed behaviour of --default-plugins (it adds conversion plugins regardless)
* Added emotionModel [sic] and emotionConversion models

//TODO add conversion tests
//TODO add conversion to docs

Use git to automatically fetch the version

* Added interactive debugging
* Better exception logging
* More tests for errors
* Added ONBUILD to dockerfile
  Now creating new images based on senpy's is as easy as:
  ```from senpy:<version>```. This will automatically mount the code to
  /senpy-plugins and install all dependencies
* Added /data as a VOLUME
* Added `--use-wheel` to pip install both on the image and in the
  auto-install function.
* Closes #9

Break compatibilitity:

* Removed ability to (de)activate plugins through the web

Closes #8

See merge request !9

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

* Replaced gevent (testing)
* Trying the slim python image (1/3 of previous size)

This should help with performance issues with models that have large
private variables.

This allows for better framing when two entries have the same @id
