Simple form for making a new order.

Updated the model with the new entity as well.
Fixed a wrong label.
Stripped a too long code line.
Moved javascript code to independent files

Also reordered the static folder.
Added return statements

They worked without them, but the explicit return
makes reading the code easier.
Added status field to Order

Also created a new "static" field with the value
for new orders, and a method for retrieving them.
Simple alert for new orders

It only shows for admin users, who now aren't shown
the link for making new orders.
