[Derision]

If you type:

#rules store

while in game, that should create rows in the rules_values table for all the ones that are missing and therefore using the defaults.

EDIT: The downside of using #rules store is that it wipes out the notes column, which contains a description of what the rule does, but if you look at the source, common/ruletypes.h has a description of what a lot of them do.
