Lots of clean up for loquacious prompt

- Move zle keymap select code to prompt module
- Use vcs_info to get repo information
- Reduce number of functions required to generate prompt
- Set $PS1 once in setup to a bunch of $PS1_* variables. These variables are set
  before each prompt. Doing this lets me change prompt themes more easily.
