  * - basic hatfile library supports concurrent access to multiple files
  - several hooks for a haskell library added to detect.c/observe.c and common
    library (haskell library not yet included)
  - bugfix: cyclic structures in hatfiles no longer lead to infinite loops.
            structures are "cut off" at a certain depth when being displayed,
            detect.c now "detects" loops (and avoids them) when searching a
            hat file.
  - name clashes: obsolete functions in browsercomms.c were commented out.
    necessary due to name clashes with hatfileops.c, when haskell files using
    the haskell interface to hatfiles are compiled for tracing.
