**Branch is in progress - DO NOT MERGE** - 9/22/2014 - ConstableBrew

- [ ] DTO classes for `MudObject`s
- [ ] Console command to create full game snapshot
- [ ] Console command to load game snapshot

The script files are located in an actual directory `Path`, but all other usage of the variable is really just an identifier for the objects (e.g. the `Key` in `NamedObjects` and the unique identifier in the DB).
