'Underscorejs snippets' added. A snippets plugin with most of the underscore.js functions available.

https://github.com/AntouanK/sublime-underscorejs-snippets

Created this plugin to complement the already existing one by 'carlo' because of the way it invokes the underscore functions, e.g.:
_(list).object([values])

Current plugin : 
_.object(list, values);
