Implement loading and exporting of Unity binary file format

[Greenlock]

Modicite needs to be able to load the Unity (non-executable) binary files into a human-readable format so that we know what can be changed in the game. Later we will need to be able to save these files with our changes for mods.

Modicite.Unity.Serialization.UnityFile can now load these files according to the specs provided by the DisUnity project by ata4. Modicite.Construction.UnityFileConstruction can convert a UnityFile instance to a directory containing the human-readable data in the form of Unity Binary Markup Language (.ubml) files.
