Cleanup
Removed "dependenies" parameter in sample config - it has not been used since 56121dfe7b6da36fc34d43f13059d4345704f0c9
Removed unused dependencies from package.json
Smarter parsing of MediaWiki links in the edit comments. (Issue #2).
Removed goo.gl url shortening - wiki.tf/d2: is short enough for us.
