  fix [modification]type=key

Previous it couldhappens that create_engines and depcheck::manager s lis
of mods could get out of sync which caused wrong modification to be
active.

Also we add a type= key to [era]s chiech defaults to mp so that only the
default era is avaiable in sp by default (for technical reasons there
must be at least one era avaiable in sp.
