Added a new jQuery plugin to deal with ajax form postback
Removed references to the old jQuery libraries in Login page
Added display informations to some models and solved a conflict
Completed the page for creating club register applications

Notice I only completed the "page". Not the logic.
Renamed goBack.js to helpers.js to let it contain all the tiny js helpers

I also added a handy function to implement placeholder texts for text
inputs. And now the search bar is using it so you can see the effect
once you merge you changes.
