Extended "ajaxvalidate", new attribute "fieldName"

[PerseusTheGreat]

In some development scenarios, developers have to change input[id|name] in different web pages.
Current situations, enforce developers to make input-specific async server validation process for each input[id] or input[name].
Sometimes this server validation process is repetitive and they can not make/write their codes reusable.

By adding new "fieldName" property to "ajaxvalidate" custom validity rule core object, developers can make server codes more reusable and independent from client input[id|name].

Usage 1:

<input type='text' 
    id='Text1' 
    neme='UserID'
    data-ajaxvalidate='path to async server validation handler' 
    data-ajaxvalidatefield='Username' />

Usage 2:

<input type='text' 
    id='Text1' 
    neme='UserID'
    data-ajaxvalidate='{ url: "path to async server validation handler", fieldName: "Username"}' />
