lib/browser/GraphBrowser/AWTFontMetrics.java

centralized handling of built-in types and constants;
also store types and constants which are rewritten during preprocessing;
interfaces are identified by classes (supporting inheritance, at least on the level of built-in symbols);
removed term_eq in favor of type replacements: term-level occurrences of type bool are replaced by type term_bool (only for the translation)
