Document core design philosophies

[MythicManiac]

It could be a good idea to document our core design philosophies to guide our design choices. Something to start off with listed below.

• Put developers first
• The CLI should be an effective tool for mod package development
• The CLI should be an effective tool for mod package management
• Mod managers should be able to rely on the CLI for their functionality
• The GPM project should completely take care of
  • Dependency management
  • Package building
  • Package publishing
  • Package distribution
  • Package downloading
• The GPM project should facilitate package installation
  • Package installation should be kept versatile and extendable

You're right, it is time we create the README files for this and eventually the wiki.
