Updated the new site setup instructions with a note to add the new
site's id to the ASKBOT_PARTNER_SITE_IDS list (otherwise it won't show
up in "Post at partner sites" list).
When admin/mod adds a new group to an user's list of groups, update the
list on the page.

Now that delete controls are showing up (to remove user from a group), fix the html (put them in their
own column so that they line up accross rows) and add a screentip. Also
requres css fixes (to follow in knowledgepoint-theme).

Merge pull request #273 from knowledgepoint-devs/modal

**This requires css fixes** Fixing auto-refresh for user profile group add, exposed group removal button which works well but needs css fixes (fixed for KP but not askbot). Also added latest step to site setup instructions.
