.val() documentation should mention radio buttons

[Chealer]

http://api.jquery.com/val/ contains:

For selects and checkboxes, you can also use the :selected and :checked selectors to get at values. For example:

// Get the value from a dropdown select
$( "select.foo option:selected").val();

// Get the value from a dropdown select even easier
$( "select.foo" ).val();

// Get the value from a checked checkbox
$( "input:checkbox:checked" ).val();

// Get the value from a set of radio buttons
$( "input:radio[name=bar]:checked" ).val();

Since the example covers radio buttons, the description should read:

For selects, checkboxes and radio buttons, you can also use the :selected and :checked selectors to get at values.

I agree about the mention of radio inputs, and would also like to see some other cleanup there:

• Replace all use of nonstandard :selected with standard :checked
• Replace nonstandard :checkbox with [type=checkbox]
• Replace nonstandard :radio with [type=radio]

@Chealer would you like to submit a pull request?

Commit 61ffc08 solves the issue I reported.

I extracted @gibson042's proposals into #993 as the PR #987 covered just the originally reported issue.
