jQuery.map:jQuery.uniqueSort: Accept array-like input, fix typos

Changes:
* `jQuery.map`: Accept array-like input
* `jQuery.uniqueSort`: Accept array-like input, fix typos.
    Apart from array-like inputs being officially allowed in
    `jQuery.uniqueSort` now, in a few places in examples
    it used to be referred to as `unique` instead of `uniqueSort`.

Closes gh-1214
