Created a DSC Resource for keeping Git repository in sync

Written this to keep a local git repository in sync with a remote repository. Planning to use for dev/test environment. 
I've tweaked the script  so it can specify the -chocolateyPath through the resource, by pulling apart the chocolateyInstall.ps1 and invoking the necessary bits.

Hopefully a reasonable solution, I don't want to reach too much further down into the choco install process for fear of pinning the provider to the current release. 

Sound like a reasonable compromise?
