Add module id information.

[ufoloko]

This PR add module id information to module settings and module label.

Sometimes, module id information is needed to add an as an anchor link, or simply to locate this module.

This code add a new row in module settings to show a label and a text with module id.

Additionally module id was added in module actions script, to show it next to de module label.

I hope this code can be helpful for the platform.

Sorry if im skipping something for the PR, but is my first time pushing code for the solution.
