Bug 12101 - Move Greybox library outside of language-specific directory

Bug 12101 - Move Greybox library outside of language-specific directory

This patch moves the Greybox library to intranet-tmpl/lib so that it is
not duplicated for each set of translated templates. The Greybox library
files are called directly only by one include file, greybox.inc, which
is modified by this patch.

To test, apply the patch and view any page which calls the Greybox
library and confirm that modal windows are still generated correctly.

For instance, Cataloging -> Cataloging search, click the "Preview MARC"
link.
