Patch #139: A bunch of fixes and nitpicks to improve the subsite awareness of the acs-subsite package, and improve support for ad_context_bar. Note that fixes needed in acs-subsite/www/admin and /permissions are not included, and that there is still quite a bit of I18N work to be done in acs-subsite.
removing large commented out pieces of code from home.tcl, I18N: moving the default texts for screen name and portrait title into the message catalog. As a result, nvl / coalesce was no longer needed and I could remove the home-oracle.xql file
