some changes to get the tab-widget working:

- the template is saved in the app_session for process_exec and not read again from the db
- extensions can request (trough $templ->loop = True) to have an other loop through exec process_exec (e.g. to show an other tab)
- extensions can have persitant data (via app_session) in $GLOBALS[phpgw_info][etemplate][extension_data][<extension-name>]
