Update the show team view.
Add a role attribute to the users (And CanCan to do something later).
Set a redirection to a random team instead of listing all the teams.

I mean, the teams are listed on the index page, we don't need this anymore.
Minor cleanup.
I hope this works.
Damn you heroku
Come on
!
Merge branch 'master' of https://github.com/codigociudadmx/ccdmx

Conflicts:
	.gitignore
Disable the apps entry on the main menu.
Add a description field to the user model.

Also, we do some more cleanup of placeholder text.
Add some extra attributes to the users and teams.

Now they have a description field.
