[antlr-interest] Freemarker grammer w/ JavaScript target

[Gerald Rosenberg]

Although your editor's approach is line at a time, no reason to try and 
force Antlr to do the same.  Antlr is more than fast and light enough to 
re-parse the entire source file between each keystroke and walk the AST 
to provide highlighting info (and walk the AST to adjust error markers 
and to collect code assist hints and ... ).
