bootstraped project/new

New layout for projects/new based on our bootstrap. This layout can be viewed on this link: http://bootstrap-catarse.webflow.com/form-send-project

Some points to consider:

1 - To test this layout I had to change the controller on app/controllers/projects_controller.rb adding the layout 'catarse_bootstrap'. I assume that this can break other pages.

2 -  For the how_know input I hard coded a collection to simulate the check boxes. Since this is hard coded I assume that is the cause for the form stops working! :D 

3 - Based on the layout that we are supposed to immitate, a feature of the simple_form breaks everything. Since that the simple_form has its own rules, I could not change the order that it generates the code. Because of that, the "hint" is appearing below the inputs. Can we easily change this or the better way to solve this problem is to ask our designers to change the layout?
