The Keyframe Update

Keyframes make the engine run at a usable speed for big worlds. To take advantage, either use ELiDE's new grid generation feature to make a new game (should be automatic), or instantiate a Character with a networkx graph as its initial state, eg.

 engine.new_character('new', nx.grid_2d_graph(3, 3))

A grid view was added to the ELiDE frontend. It should mainly be used with Characters generated as above.

There are some subtle changes to the quickstart tutorial in the README.

This isn't a new feature, but I want to draw attention to a section of the manual that I didn't mention last time: Input Prompts for prototyping actual interactions with the user.
