updated sgt api
fixed wrong matching of components
rethrowing errors encountered in autorun files so they are logged to the event log; allowing pure string tables (i.e. Map<String, String>) in signals. may extend this to further types at some point, but for now that'll have to do
Merge branch 'master' into sgt
added empty "base" mod that acts as the owner of the api to avoid cyclic dependencies
avoid defaulting abstract bus cards to disabling when loading before they were saved at least once
