Issue #488 Implementation of teams - Corrections (again)


Hi,

I solved the problem of local navigation to the anonymous user. Now an anonymous user only will see:

And It could obtain detail and members of this public team:

What else? I've changed the navigation to a authenticated user, now it could create a new team, view its signed teams of public teams.

Note, the admin user will have another issue to see private teams to modify its settings or members.

When a user create a team will see the next page:
![github08](https://f.cloud.github.com/assets/3799414/568437/e541c436-c6d8-11e2-8182-8a417a1150b5.png)




I hope you like it this new version of teams
Best Regards
