=== very important changes ===

In the pretty printer, a direct "write" call has broken internal position 
counting. This is now fixed, and the overwrite internal positions options
now works fine for start positions. This is important for graphical frontend
that can now find the exact start position of a token after displaying the
pretty printed output.

Added a method for Java compile time control flow analysis to SourceInfo
and some auxiliaries to StatementKit, including the very convenient
ControlFlowWalker.
This allows to find out whether the end of a void method or a constructor
or initializer is reachable: it is not admissible to insert statements that
cannot be reached.

--- quite important changes ---

Refactored PrettyPrinter interface: removed unnecessary internal functions
thereby reducing recursion depth, renamed printInternalIndentation to 
printElementIndentation, folded duplicated code.

--- negligible changes ---

Added a new interface for ProgramElementWalkers, now implemented by
AbstractTreeWalker.

Minor patches in XReferenceHTMLGenerator: creates output directory when 
needed; underlining was broken for "new"; references are now contained in 
only one "X.html" file and entries are joined globally - the total size is 
decreased somewhat.

Added a starters' tour to the home page, linking to example sources
and generated html input and output pages. This increases the size of
a distribution a bit, but should attract more people.
