Added clean/dirty characters for git repositories

[alexdebril]

Hello,

I added a few lines to deal with git repositories in the gnzh theme :

• a green ✓ when it's clean
• a red ✗ when it's dirty

This is how it looks on my terminal:

Hi folks. There's a new PR #4113 for an eval-related problem in gnzh that interacts with this PR. If #4113 gets merged, change this:

GIT_CLEAN_COLOR="%{$fg[green]%}"
GIT_DIRTY_COLOR="%{$fg[red]%}"
ZSH_THEME_GIT_PROMPT_CLEAN=" $GIT_CLEAN_COLOR✓"
ZSH_THEME_GIT_PROMPT_DIRTY=" $GIT_DIRTY_COLOR✗"

to this.

local GIT_CLEAN_COLOR="green"
local GIT_DIRTY_COLOR="red"
ZSH_THEME_GIT_PROMPT_CLEAN=" %F{$GIT_CLEAN_COLOR}✓%f"
ZSH_THEME_GIT_PROMPT_DIRTY=" %F{$GIT_DIRTY_COLOR}✗%f"

(Even if #4113 doesn't get merged, I think this theme should be resetting the color at the end of the ZSH_*_ variables anyway; I'm not sure it's guaranteed to be reset for you by the git prompt functions.)

Whatever happened to this? I really like gnzh but would like more git info.
