Rename plugin class

[iGitScor]

Hi,

According to Webpack team:

3rd party Plugin names should be foo-webpack-plugin for pkg name and FooWebpackPlugin for class

The package will not be renamed for now but we have to change plugin class.
It should keep compatibility with previous class name.

Task list

• Add class alias
• Change documentation
• Write new test case

If you find another side effect, do not hesitate to correct it

Thank you
