Use zstyle for configuration

[ericbn]

instead of "global" environment variables.

From the "(z)style" glossary entry of From Bash To The Z Shell:

style

In zsh, the style mechanism is a flexible way of configuring shell add-ons that use functions, such as the completion system and editor widgets. Unlike variables they can be different in different contexts and unlike shell options they can take values. The mechanism is based on the command style.

@Eriner, I want to use zstyle for all the zim configuration, as we already use in the git-info module. Two advantages are:

• configuration is isolated, instead of "globally" taking up the environment variables space.
• zstyle provides utilities to read values that are arrays, strings, booleans, etc. See http://zsh.sourceforge.net/Doc/Release/Zsh-Modules.html#index-zstyle

I'm taking advantage of zstyle also for the modules configuration in the new distributed code. For example, this is how you would define them:

zstyle ':zim' modules \
    zsh-autosuggestions directory environment git git-info history \
    input ssh utility completion zsh-syntax-highlighting history-substring-search

zstyle ':zim:module:zsh-autosuggestions' url zsh-users/zsh-autosuggestions
zstyle ':zim:module:zsh-syntax-highlighting' url zsh-users/zsh-syntax-highlighting

What do you think?

Yes, this is fine. Let's take this off the master branch though -- I don't want to break anything for anyone else.

Derp, this is in a module. LGTM.
