New login2

updating fields in login page 2, controllers and views updated.
same here: ` Skill.all.map {|s| [s.name, s.id]} `

Better to refactor this as a class method and then use the class method, so something like:

```ruby
class User < ActiveRecord::Base
   ....
   def self.for_multi_select
      Skill.all.map {|s| [s.name, s.id]}
   end
   ....
end
```


Then in your view:

```ruby
<%= f.select :want_skills, options_for_select(Skill.for_multi_select), {}, :multiple => true, class: "form-control" %>
```
