Consider making core provider references not need array-indexing

[iislucas]

Currently core providers are entried in freedom with the prefiex core.; unfortunately, this makes them impossible to be given clean type interfaces (strongly type systems do not allow multi-type arrays as multi-typed collections are bad coding-style: indexes are not food syntax to indicate type).

It would avoid the need for a gross hacky rename prefix file for that binds every core.XXX to core_XXX if freedom just used the core_XXX style to start with. Or even better: freedom.coreProviders.XXX and freedom.providers.XXX and freedom.rawModule.XXX (for just on/emitable things).

What do you think? :)
