Add garrett theme

[sorin-ionescu]

Evaluate and embed @chauncey-garrett's https://github.com/chauncey-garrett/zsh-prompt-garrett as an external theme.

I'd be honored to have my theme as a part of Prezto. Let me know if there's anything I can do to help.

If you don't want it to be an external theme, you'll have to use Prezto's coding style. If you want it to be faster, look into asynchronicity for Git; see, #796, #892, and #888.

I'm definitely interested in making the prompt faster while in a Git directory since there is a slight but noticeable delay (deciseconds scale). However, I won't be able to work on this anytime in the near future (that's not to say I won't eventually take time to work on speed improvements).

In the meantime, if someone wants to tackle it: PRs accepted!

Are we talking just tabs to 2 spaces (which I'm starting to like more and more) or more than that?

If you don't want it to be an external theme,

May be best to keep it external for two reasons:

1. It's more complicated that most other prompts I've come across -> I'll be able to handle issues directly
2. I'd like to add asynchronicity for Git at some point in the future

The coding style refers to more than spacing. You'll have to read the code to get a feel for it.

I don't mind keeping it external.

Just discovered this theme, it's nice :+1:

@habitullence Thanks! :)

@chauncey-garrett Thank you :) Did you get a chance to look at async? If not, I'm trying to learn zsh. Would be happy to take a look at it if you can point me in the right direction.

[chauncey-garrett]

@habitullence I haven't had the time of day but it's still something I'd like to incorporate. See @sorin-ionescu's first comment in this thread that includes several conversations around doing so.

@sorin-ionescu It's still not in external, is it? At least I don't get it during update.

This was added to an experimental contrib repo in https://github.com/belak/prezto-contrib/commit/8ced528185d9d4c7bffd37d6fc290e3099616870

Any news on this one? Still not merged?

[msubel]

I'd love to see this merged as well. Garrett is the most useful prompt I've seen
