Merge pull request #11 from gregf/master

Update CHANGELOG and add Greg Fitzgerald (@gregf) to contributors
Release version 1.0.5 with Grafana 1.6.0
Add emeril for easier cookbook releasing process
Bump to 1.0.6 for first community cookbook release
Used some common naming conventions for included recipes
Tighten permissions on config file
Install via file type over git.

Using git master could easily break in between releases. Using the
file method lets us stay on a stable release. It makes the most
sense for a default.
Switch from zip to tar.gz for the default file type.

This makes it so we don't need to install unzip to extract the file.
Most if not all linux servers will come with tar installed.
Add some comments to attributes to help organize it
Block access to config.js from the browser.

config.js could contain username and passwords for graphite and may
contain more sensitive information in the future.
Use /srv rather than /opt

According to FHS /srv is the proper location for www, ftp, and any
other data served by the system.
