Item12849: implemented support for new ACL style since Foswiki >= 1.2

also:
- fixed shebang in several scripts
- fixed syntax error in Config.spec
- don't use global DEBUG variable as it clashes with Assert.pm
- fixed dependencies to really require all required extensions
- removed dependency on WebLinkPlugin as FlexWebListPlugin can do web titles on its own now
