Custom selector and fix for change event

[claviska]

859a7ae fixes your todo item at the bottom. It shouldn't affect speed since nothing in the loop changed.

01f76c5 adds a custom selector option, similar to what was suggested in #6.

I've modified the code for clarity and tested it on a list of about 2,100 items. Compared to the original version, there appears to be no noticeable difference when a selector is not specified (i.e. the default, backwards-compatible behavior). As expected, however, there is a nominal performance hit when using a selector. (I've noted this in the readme for prospective users.)

I believe this will be useful for a lot of people. My use case is something like this:

<ul>
    <li>
        <span class="badge">Badge Text</span>
        <span class="description">Description</span>
    </li>
</ul>

By default, the filter will compare against Badge TextDescription, which is undesirable. But when .description is used as a selector, the plugin compares only against Description, which is the desired behavior.

7ad6fcd removes the use of addback(), which was benign but unnecessary and would have made the plugin incompatible with jQuery < 1.8.

Is this plugin still being maintained?

Sorry, been a bit busy. This change looks fine to me, I'll merge it in.
