5a instruction
A bit more useful name for the bytecode
Fixed invokeinterface

Actually it's not fixed. It's still erroring and I'm not sure why.
Working on reading the code so I can understand and fix it. But I fixed
one part of invokeinterface!
Updated readme since lasm is now included
Fixed Computer.pullEvent and implement no-filter version.
So there may have been some silly mistakes in the test.java program... All better now!
Fixed invokeinterface. You have to use findMethod at runtime.
Fixes #7

Invokevirtual works by finding the method in the object's particular
method table (which itself is just a reference to its class's method
table)
Made invokeinterface slightly more correct.

Should be using asmGetFTInfo()
