1.1.5:
	o added link to best-of list which shows the detailed
	  results (stats) for the user.

1.1.4:
	o changed database type from DB_File to GDBM_File so
	  one can use dbtool to manage the result databases.
	  while dbtool supports berkeley db too, it is in
	  most cases compiled with gdb support.

	o fixed bugs in the answer computation code

	o added result/statistics at the end of a session
	  stats are stored in stats.db during a session and
	  removed afterwards.

	o time counter returned by javascript code will now
	  completely ignored. the 'starttime' cgi variable
	  is the important one.

	o some cosmetics on the .tpl files

	o simplified config format for choices.
