parsing template-ids: enables clas template partial specializations and fixes 54778 indirectly
- add ITokenDuple.getTemplateIdArgLists
- Added ExpressionParser.templateArgumentList & ExpressionParser.consumeTemplateArguments
- modifications to ExpressionParser & Parser to parse template argument lists
- modified lookups to lookup with template-id if the token duple has argument lists
- modified TemplateFactory to handle partial specializations
2004-03-17 Andrew Niefer
fix bug 55163
- in for-init-statement, try expression-statement before simple-declaration since if it actually is a statement instead of a
