Fixed issue on password fields: original class attribute is not cloned into fake input

I noticed another little issue on password fields. I'm styling all my inputs via class name, something like:

    <input type="text" class="skeuomorphic" name="username" placeholder="Your username">
    <input type="password" class="skeuomorphic" name="password" placeholder="Your password">

Using your plugin, my password fields are not styled until focused. I noticed that is because you create a fake *text input* in the place of the password field, but without copying existent class attribute on it. Refering to my previous example, the generated HTML is:

    <input type="text" class="skeuomorphic placeholder" name="username" placeholder="Your username">
    <input class="placeholder" tabIndex="-1" value="Your password" type="text">
    <input type="password" class="skeuomorphic" name="password" placeholder="Your password" style="left: -9999em; position: absolute;">

The 2nd element should have class *skeuomorphic* **and** *placeholder*.

**NOTE:** I updated the minified version too, using YUI Compressor: it's now a little bigger than yours (and not only for my addition), maybe you used a better minifier. The problem does not occur in the *2.0 beta* version.
