changed to only fork a thread if number of rows in spreadsheet is > 500 (so small spreadsheets don't have to wait for status page's first update if<5 seconds)
LDEV-1261 improve import user speed by running in separate thread (bypass hibernate filter), and update browser with progress every 5 seconds so it doesn't timeout.
Missed adding the system tool for the System Gate. As a result, if the user tries to go to the gate, they just get the index screen. The problem will have gone out in the Windows upgrader. Doing this fix now and will be okay in the Unix upgrader.
LDEV-1257: Added support for Groups to be created in authoring (so that the names can be entered) and the mapping table to map groups to a sequence activity (ala branch) for a Group based branching activity.
LDEV-881: Another attempt to get rid of the java.lang.ArrayIndexOutOfBoundsException: 1 warning. This change should avoid many warnings coming out of Tomcat - not what we really wanted but we need to get rid of the "java.lang.ArrayIndexOutOfBoundsException: 1" warning as it really clutters the logs.
LDEV-1261 remove import spreadsheet actions from customised hibernate filter - need to enumerate each url in lams_admin that requires the filter from now on
