Refactor of codebase

Created by: perploug

This is a major refactor of the codebase to follow better practices, enable unit testing and using the evidence collector as an API rather than a standalone application.

• backwards compatible, no breaking changes to the current application
• abstracted all functions into 3 parts: collection, inspection and reporting
• everything now depends on injectable input which enables testing
• codebase is split into an application and a library
• Fixed issues with shared resources (such as the logger) which prohibited running the collector multiple times in the same thread.

This version is currently used in a production setup and should provide the same results as the current code base Unit testing is only partially done, but can be improved over time to increase coverage
