ACCodeSnippetRepositoryPlugin_Fixed

This is a fixed edition for ACCodeSnippetRepositoryPlugin for support Xcode 7.2 and above.

1.Fix issues:

1. Fix MenuItems (I move the menuItems to 'Source Control' menu from 'Plugins' to avoid plugin conflicts); 

2. Fix Snippets Path (Because Xcode 7.2 no longer recognize snippets in subfolders,
                     and I change the path to ../CodeSnippets/ ).

2.ReactiveCocoa and PromiseKit codesnippets from myself:
