major cygwin bugfixing

The init-script-testsuited uncovered many problems running this script
on cygwin/windows 7. This patch removes the following problems:
- If paths used for starting the jvm contain trailing backslashes the
  script does not work properly because quoting problems
- the path for the pidfile was not also problamatic regarding paths
- removed not neccessary variables
- quoted some paths/variables
