Fix session expire handling

If session has expired, hide entire UI (except for dialog) to prevent
clicking/seeing expired UI elements.
Fix Externalization of hard-coded label strings

-Split 'dictionary.jsp' into two files -> 'dictionary.jsp' and
'dictionary2.jsp' -- this is due to JSP file constraints as the
localization object is getting quite long

-Per change above, 'dictionary' object is now split into an additonal
'dictionary2' object, which is merged with the main dict object on page
load

-All new dictionary mappings should be added to 'dictionary2' now.
