In addition, fixed some problems to make it compilable under Smalltalk/X:
* Fixed PPCTokenNode>>initialize - there's no children instvar, it's initialization removed.
* Fixed PPCContextMemento>>propertyAt:ifAbsent: - removed return-in-return, not compilable under Smalltalk/X (C issues)
* Fixed PPCContextMemento>>hash - there's no stream instvar, access to it removed.
* Fixed PPCAbstractCharacterNode>>compileWith:effect:id: - removed dot after method selector (stc does not like it)
