r20399: More SWAT updates

The LDB Browser has now been rewritten as a SWAT module.  That brings the
current number of modules to three: Samba Statistics/Status, LDB Browser and
API Documentation.  This should provide a good working example for Brad and
his class, for how additional modules can be added.

The basic infrastructure for SWAT is now entirely in place.  Next step is to
deal with putting the qooxdoo developers' kit someplace, as it is required for
making changes to SWAT, and reorganizing the swat directory hierarchy to
remove (or move to elsewhere) a bunch of old cruft.  The final step will be
ensuring that SWAT installs during a Samba build, so that it becomes useful.
(Much of this "next" and "final" step stuff will likely have to wait until
after New Years.
