Fixes zsh-users/zsh-syntax-highlighting#156.

You cannot download just the "script". You need the entire directory/repo.

Edited links to Archlinux packages (the link to `zsh-syntax-highlighting-git` is out-of-date, and `zsh-syntax-highlighting` is now available in [community])

(Anyone knowing packages for other systems or wanting to create it,
please get in touch!)

* Don't override user defined styles
* Better modularisation of highlighters
* Allow to define which highlighters are activated
* Allow to define the order in which they are defined
* Minor performance optimizations
* Fixed some variables leak
* Improve documentation
* Brackets highlighter: use ZSH_HIGHLIGHT_STYLES instead of a specific array

The script still works on its own, highlighters in highlighters/ are
loaded as addons if present.
