/**
 * This plugin inserts the right avatar for the user, depending on, whether a
 * custom avatar is uploaded - which it uses then - or not, and display a
 * placeholder with the first letter of the users name instead.
 * For this it queries the core_avatar_get route, thus this plugin is fit very
 * tightly for owncloud, and it may not work anywhere else.
 *
 * You may use this on any <div></div>
 * Here I'm using <div class="avatardiv"></div> as an example.
 *
 * There are 5 ways to call this:
 *
 * 1. $('.avatardiv').avatar('jdoe', 128);
 * This will make the div to jdoe's fitting avatar, with a size of 128px.
 *
 * 2. $('.avatardiv').avatar('jdoe');
 * This will make the div to jdoe's fitting avatar. If the div already has a
 * height, it will be used for the avatars size. Otherwise this plugin will
 * search for 'size' DOM data, to use for avatar size. If neither are available
 * it will default to 64px.
 *
 * 3. $('.avatardiv').avatar();
 * This will search the DOM for 'user' data, to use as the username. If there
 * is no username available it will default to a placeholder with the value of
 * "x". The size will be determined the same way, as the second example.
 *
 * 4. $('.avatardiv').avatar('jdoe', 128, true);
 * This will behave like the first example, except it will also append random
 * hashes to the custom avatar images, to force image reloading in IE8.
 *
 * 5. $('.avatardiv').avatar('jdoe', 128, undefined, true);
 * This will behave like the first example, but it will hide the avatardiv, if
 * it will display the default placeholder. undefined is the ie8fix from
 * example 4 and can be either true, or false/undefined, to be ignored.
 *
 * 6. $('.avatardiv').avatar('jdoe', 128, undefined, true, callback);
 * This will behave like the above example, but it will call the function
 * defined in callback after the avatar is placed into the DOM.
 *
