Hidden field options for edit and create forms + Input Names + Grunt

This is replacement for field type = 'hidden' which I found too restrictive. 

Creates two new field options:
editHidden: [true:false] 
createHidden: [true:false] 

Removes type option:
type: 'hidden'

Notes: Also allows to override field value with defaultValue.

Usage
 
           CreatedDate: {
                title: 'CreatedDate',
                type: 'date',
                displayFormat: 'dd/mm/yy',
                editHidden: true,                          /* optional 
                createHidden: true,                      /* optional 
                defaultValue: '11/11/1111'             /* optional            
            },

Update: 
Created a new field option:
inputName: 'newInputName'

I needed to add this option to easily override the default input name. This is support Ruby on Rails way mapping posts to an ActiveRecord object. 
eg.    name="student[firstname]"


Usage

            FirstName: {
                title: 'First Name',
                inputName: 'student[firstname]'         
            },

Thanks for looking again
