/**
* 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 aready 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.
*
