Requests library is not included in the requirements

Issues:
Fixes #21

Problem:
The requests library was not included in the setup.py as a requirement
so after installation when you tried to use the iControlRESTSession
it would error because requests was not found.

Analysis:
* Added the requests library as a requirement
* Fixed some formatting issues and updated the author name to be
  F5 Networks.

Tests:
* Created the package
* Installed the package and verified requests was there
* Instantiated an iControlRESTSession object with no errors.
