[Validation] - Make Identifier Optional

[avalanche1]

Form validation code would be DRYer if we could omit specifying field name two times.

.ui.form
  input(name='category') Select category

Instead of:

$('.ui.form').form
  fields:
    category:
      identifier: 'category'
      rules:[
        type: 'empty'
        prompt:'Specify a category']

I propose by default:

$('.ui.form').form
  fields:
    category:
      rules:[
        type: 'empty'
        prompt:'Specify a category']

In case user needs to have differing fieldname and identifier name - he can explicitly specify identifier.

I think this makes sense as an enhancement. Allow both

Identifiers are now optional.

I've added a new form shorthand that works like this

$('.ui.form')
  .form({
    fields: {
      name     : 'empty',
      gender   : 'empty',
      username : 'empty',
      password : ['minLength[6]', 'empty'],
      skills   : ['minCount[2]', 'empty'],
      terms    : 'checked'
    }
  })
;

Will automatically expand out to full validation settings using default prompts and matching validation identifier against property.

@jlukic, Thank you for your hard work

yay! thanks, Jack!
the next best thing for Validation would be allowing assigning the same rule to multiple fields: #667, #829

[jlukic]

I was hoping to do that as well, but there are complications with how it's handled internally.

Can one keep a copy of the "fields" object and alter "prompt" to change the actual error message displayed?

Alternatively can "prompt" optionally be a function that returns the error message?

It seems the shorthand version could not be used in conjunction with the full version for validation rules. It would be more reasonable to be flexible in these forms.
