non existent dependency management

[hayesmaker]

There's no way to tell what versions of plugins you downloaded and put into the plugin folder.

eg. open https://github.com/gurayyarar/AdminBSBMaterialDesign/blob/master/plugins/sweetalert/sweetalert-dev.js

no version number is mentioned.

you need to get dependencies either from npm or bower to keep some sanity in projects like this. And this is why so many people are reporting issues.
