* Make DocFunction not a RuntimeException, and throw it only where needed.
* Add TokenStreamInjector class to rhino to make TokenStream publicly available
* Add StringUtils.splitLines()
from http://dev.helma.org/Wiki/Rhino+Bugs+%26+Patches/:
- Rethrown exceptions rendered as [object Error]
- Provide protected callback methods in Rhino debugger SwingGui
- Bug in tail call optimization that cripples Rhino debugger
* Remove old Rhino 1.5 classes, make Helma debugger subclass Rhino 1.6 classes
(not fully functional yet, needs patches to Rhino debugger).
* Make helma.doc.DocFunction compile with Rhino 1.6 by introducing intermediary
DockenStream class that proxies TokenStream using java reflection.
