Accept vi-end-of-line

Avoid bell on all keysrtokes

fix for AUTOSUGGESTION_ACCEPT_RIGHT_ARROW in vi-mode

Due to using a forked version of zsh-syntax-highlighting, you also get along the bug that causes a [bell on every keystroke][1], using zsh-users/zsh-syntax-highlighting instead I avoided this bug.

Support OMZ

LGTM!

It basically means this: go to the end of line (i.e. accept the
suggestion) and then hit enter.

Improve readme

LICENSE (optionally with an file extension) is a common file name for
the license file.

.md is a preferred file extension for Markdown files.

Fix indentation in autosuggest-backward-delete-char()

Fix and unify formatting and code-style

See http://www.editorconfig.org/

To work better with recent version of zsh-syntax-highlighting.

Updated readme with more configuration options.

User can also supply as a first parameter the script to append to
zsh-autosuggestions.

Simplify installation instructions

My rational for this is:
 1. Most linux desktop users are using some kind of debian/ubuntu/mint, so why not have them catered for primarily?
 2. the bash instructions work for everyone who has bash. Last time I checked, that was 99% of the linux community.

Added clarification to use bash

Some linux distros have sh symlinked to dash. So I have added a clarification to use bash for the distros.

Update README.mkd

Fix the path.

Fixed: installation on OS X fails

Fixed #38
