MyTasks portlet improvements and fixes:

- Inner panel of MyTasks portlet now a separate webscript called 'mytaskspanel' and an ajax request is used to refresh or update the panel after an action occurs.
 - Generated task actions fixed to use ajax refresh rather than full window refresh (fixes issue with MyTasks portlet actions being used in JSF-168 or JSF runtime)
 - Generated task actions fixed to handle default (null) transition ID
Permission checking added to MySpaces portlet actions.
