[rules-users] Speed up inserting of rules into knowledge base

[Corneil du Plessis]

You should only repeat

knowledgeBuilder.add(resource, ResourceType.DRL);

for each rule.

The next thing you can do is to serialize the compiled rule packages.

You should also consider using Guvnor to manage your rules.
