Fixed Group avatars to only display when user has read
permissions to at least one project in the group.

Before we have only owner_id to determine group owner
With multiple owners per group we should get rid of owner_id in group.
So from now @group.owner will always be nil but
@group.owners return an actual array of users who can admin this group

* Hooks and team pages allowed only for masters/owners
* Group page allowed for admin
* Corrent authentication for Projects controller
* Hide some project elements from visitor

Provide UI with explanation what happens when you block or remove user
When remove user - remove all groups where user is an only owner

Get rid of skipping callbacks in production code. Dont trigger gitolite more than once on import in group
