groups management

i extended the admin application with some new functions. it is now possible to create and edit groups. i also added javascript controls for adding and removing users to a group in the group edit dialog. that was another step for our accounts and groups management.

while implementing these new features i learned the basics of the mighty extjs framework and gained some more experience programming javascript.

i think we'll publish a new demo version soon. then you can at last try out the new features of tine 2.0 we have been talking about in the tine blog for the last few weeks.
