FWB-40684-webstore-module-backend

Allow fw_sig params to be sent in headers

Gives us an alternative to the existing parameter-based implementation
Also update source control management for Webs in 2014
Also should update that readme, it's over 4 years old at this point...

Also someone needs to give me (will-webs, william@webs.com on rubygems.org) push rights to this gem.
This change may be important enough to warrant version `0.3.0`

From http://semver.org/:
> Given a version number MAJOR.MINOR.PATCH, increment the:
> 
> MAJOR version when you make incompatible API changes,
> MINOR version when you add functionality in a backwards-compatible manner, and
> PATCH version when you make backwards-compatible bug fixes.

This fits pretty well with the definition of "MINOR"
