New login2

updating fields in login page 2, controllers and views updated.
I'm pretty sure the method should be added to the `Skill` class.

``` ruby
class Skill < ActiveRecord::Base
   ....
   def self.for_multi_select
      Skill.all.map {|s| [s.name, s.id]}
   end
   ....
end
```
I figured this out on my own.
