Added functionality to get AutoPkg recipe repos from GitHub API instead of static array. The array is also sorted such that the repos with the highest star count appear at the top of the table view.
Check for nil before attempting to serialize JSON data.
Merge branch 'get-repos-from-api' into master-x

Conflicts:
	AutoPkgr/LGConstants.h
	AutoPkgr/LGConstants.m
	AutoPkgr/LGGitHubJSONLoader.m
Available recipe editors are generated via LaunchService
and a popup button is populated with the results.
Thanks to @futureimperfect for the idea.
