Roadmap for v0.1.0

[arqunis]

This is a basic roadmap to get the initial release of the new framework up and running.

What needs to be done:

• Port buckets from the original framework (relevant issues: Port buckets from the original standard framework #9)
• Implement utilities for creating a help command and provide plain-text and embed help commands out of the box (relevant issues: Implement builtin plain-text and embed help commands  #10)
• Allow more complex types in the argument system that cannot work with just a FromStr implementation (relevant issues: Allow serenity model types in argument parsing system #24)
• Allow mixing the order of required and optional arguments to permit backtracking in argument parsing (relevant issues: Argument parsing for required and optional arguments should have a flexible order  #31)

What does not have to be, but would be very nice:

• Implement localisation utilities such that the user can load and use localised text painlessly (relevant issues: Implement localisation utilities #21)
