OMComputation 0.3.0

First public release, but consider it "early access" - things are not finalized, and there are features to add yet.

Added:

• Modders can create computation puzzles through the provided API. (to-do: make documentation for the API)
• "Simpler" computation puzzles can be made via a YAML file, so no C# coding required. (to-do: make documentation for the format)
  • Molecules are stored in the same format as what's used in puzzle.yaml files.

Known issues:

• Computation input/output molecule names are not displayed in the parts tray.
• Test cases not implemented yet.
