Moved XML files to Data/ dir.
Transformed X.lib files ==> lib/AN/X.pm with capitalization.
Modified an-cdb and an-mc to 'use' packages rather than 'require' subscripts.
Modified scripts and modules to use fully-qualified module names to reference
external routines.
Simplified create_rsync_wrapper() by using single quotes inside
the outer double quotes, resulting in less escaping.
remove accidental comment on initialize_http().
Now thatwe use modules rather than load libs into main::, the modules
need explicit access to each other.
