Design in-area map views

[SebastianJay]

Once in an area, the player will be able to pull up a map (of that area), which will bring up a separate window. Each in-area map will look like a graph of nodes and the edges between them.

For each area, create an ASCII 118x27 grid view of the nodes and edges in one file, and in a separate file define a mapping of area code to other data, like:

• location of node in "art" file
• title of location
• description of location
• neighbor nodes and their relative positions (up, down, left, right) -- we can likely support at most 8 directions

A small 120x3 window can show a description of the area being hovered over, and at the bottom will be a 120x1 help window (#22)

This data can be defined in YAML, which is easy to read and generate.
