If table -> value or value -> table, just do an assignment instead of an update.

Only merge if both oldmod/newmod are both tables. This could be replaced with a check inside update but since the other call paths need to check out of update I thought consistency would be better.

Only update + replace with updated value if both old and new are tables.

I found three edge cases that can lead to a crash in lurker. All of these have to do with calling
updateon a non-table object. In order of how reasonable they are:return {}return {}One of these can be solved by just checking in
updateitself, but the other two require checks before callingupdate.
