JSON areas; objects

- Areas have interactive objects (new class)
- Game loads a content file (only one room in it)
- UI tweaks
- JSON.net
Added "get" command + inventory

- Moved namespaces around
- Added delegate for a command; delegate is command(target, instrument,
preoposition)
- You can now get objects, and list them in your inventory
- Objects have "affordances" like "get" or "eat" to dictate
functionality
Remove ConsoleX.

I didn't know the standard console can do 16 colours like I want.
AWESOME.
