Add -Wall so we can see when we forget to return self (4th time it happens)
A new test for Methods
Implement MethodDeclaration node.

It's all done, we just need to deal with statements
node_create_type
node_create_paramdeclaration
node_create_methodparams
node_create_methodbody
node_create_methoddecl
New 4th child node
Fix node printing (and reorder nodes so we don't fuck them up)
This one gets us with full accepted.

I didn't bother splitting this up in commits. Fuck you too.
Also have JN's ijparser for testing
