repository cleanup and gui setup

[ivanocerrato]

Right now, there are a lot of files to move from the config folder to the proper folders to set up the gui. This is error prone and makes the configuration of the gui hard to be authomized.

Proposal: let the contrib folder as it is, but also copy the required files in the proper folders of the gui. In that folders, please add a README says that "file xy is actually part of the library AB available at URL .."

@ivanocerrato: is this issue still meaningful? Otherwise we can close it.
