Readme cleanup

Finishing touches.
That travis-ci badge doesn't look like it was ever actually setup, and the build never really breaks anyways.

Notable issues:
- The +cat example doesn't work. At all. You can't even try to type the path without breaking :dojo.
- The "Control Characters" example for ^X is a lot more lack-luster now. Instead of being able to spawn arbitrarily many console apps that wait for input, being able to kill and swap between them at will, you can only have one console app running under a :dojo instance and arbitrary other ^V app. This is bad, since if a reader is going through the file sequentially they may not have a program other than :dojo running, making it looks broken. I moved the ^V section to the top so they can hopefully put the pieces together...
- Someone should really proofread this. Make sure I updated all the hostnames and shipnames, since I had to do that manually, and that everything read well. Dammit Jim I'm a programmer not a writer...
