Logic is moved from server to client. Config is added via getSkinConfigVariables (e.g.
passed to mw.config ) and a JavaScript if statement.
The IIFE in watchstar and talk files is replaced with a module.exports function to avoid
refactoring at this point and added risk. The file contents remain the same.
skins.minerva.options is left as is, given the code is more experimental and used in
the beta mode - should not be sent to all clients.
Additional change:
* Remove skins.minerva.toggling (that module has been empty for a week now and functionality
moved to mobile.init module)
