Make replace_rules returning boolean.

Browse source 
We only use whether the return value is IMPORTANT_RULES_CHANGED or not, so we
can just return true if an important rules was changed in the function.
Also, we can just return false in case of animation rules changes sine for
animation we can ensure there is no importan rules.
Because of these changes, replace_rule_node does not borrow |result| so that
we can drop a scope there.
