Pagan

* Added simple webserver (early state, unstable) to use pagan as a web application.
* Added pagan command line interface to generate avatars from your terminal.
* Added pytest and tox tests.

* Resolved issue with newer versions of pillow.
* Resolved issue with python 3 imports.
* Resolved issue with python 3 hash encoding.
* Updated Readme.

* Implementing the Avatar class in pagan.py as the main accessor.
* Overall restructure for an object oriented approach.
* Avatar objects can now be instantiated and manipulated before drawing.
* Hash functions can now be omitted on Avatar creation by using simple constants (e.g., pagan.SHA512).
* Generator paths are now OS independent.
* Comment cleanup on some methods.
* Constants are now initialised in __init__.py

* Refactoring of the main filename from pagan.py to generator.py
* Added pathhandling for correct template reading to import pagan as a installed module.
* Hashfunction accessors are now stored in a dictionary.
* When run as main, the predefined samples run all available hash algorithms.
* Added a setup script and manifest to publish on pypi.

* Refactoring
* Cleanup

* Modified pagan to generate hashes from arbitrary input strings.
* Avatar creation is now fully based on a hash in hexadecimal form instead of IPv4 addresses.
* Supports all hash algorithms that are included in pythons hashlib.
* Can still process IPv4 addresses, they are also hashed now. Same applies for IPv6 addresses.
* Features more colors. Each part of the gear is now painted uniquely due to the potential of hashes.
* Did some refactoring.
* Added documentation.
