Add composer.lock, remove gumph

No need for Contributing file, people know how to send pull requests
and I don't have a special repo or anything. Add the composer.lock
as well so people definitely get working versions of packages.
Set version and update readme

It's about time I got round to sorting the readme, so now it has
a basic overview of what the project is about, and basic install
instructions so people can get started. All untested of course.
Merge branch 'release/0.1' into develop
Update core and abstract Youtube initialisation code

Created a new repo for the Youtube Wrapper which uses Laravel 4.1,
so updating this one to match (else conflicts). Starting off by
abstracting the loading of the Google and Youtube services.
This reduces route code from 11 lines to 4, and completely removes
another dozen from the top of the file. Still loads to do though!
Update everything to use the YtWrapper package
Merge branch 'feature/api-wrapper' into develop [closes #15]
