Provide standard way for skins to add JS config variables to page

Browse source 
Both Vector and Minerva add JS config variables. We should provide
a standard function for skins to override to do this.

This will be shortly used in Vector
(Ic9d54de7e19ef8d5dfd703d95a45b78c0aaf791a)
and immediately in Minerva
(Ia5aae659d9882bef7a273c709789437719303a35)
