Look at items and NPCs

[wesker-albert]

• add the ability to look <target> to display the description of player inventory items, items in the current room, or NPCs in the current room
• if multiple matches exist, the search target can be prepended with a number and a period, to specify which result to look at: look 2.fork
• the result list is sorted according to the priority the AC dictates: 1. room items, 2. inventory items, 3. NPCs
• refactor the Look class a little bit, for better organization and readability
• create and expose the Resources class, which will house methods the aren't necessarily associated with only one resource type

Closes #27
