[Dependency] Adding clingwrap and npm-check-updates

[nuxlli]

In order to improve the dependency management in azk (specially the npm-shrinkwrap.json update) we added the packages clingwrap and npm-check-updates.

Besides, two things were done:

• During development time (AZK_ENV=development), the commands azk (node|npm|gulp|clingwrap|ncu) are now available;
• A cleaning in npm-shrinkwrap.json was done for all packages. This caused a big change in this file, but now on, it'll be way easier to maintain it;

Finally, every single time a package is installed, updated or removed, the following command must be run:

$ azk clingwrap [package_name]
