* jode/obfuscator/modules/SimpleAnalyzer.java.in:

Ported fix from ConstantAnalyzer:
(canonizeReference): for interfaces call canonizeIfaceReference.
(canonizeIfaceReference): new method.
* jode/obfuscator/modules/ConstantAnalyzer.java.in:
made sub class of SimpleAnalyzer.
(canonizeReference): Removed, since its inherited.
(canonizeIfaceReference): dito.
