Added HTML5 Image Uploader

[kresty]

I got fed up with the old flash-based thing, so I enabled the HTML5 upload plugin, which is recommended.

After clicking "images", and "upload" (and creating an album if necessary), please choose the HTML5 uploader from the drop-down selection.

HTML5 Uploading Example
Pick "Multiple Files - HTML5-driven for the best experience!

To use the HTML5 uploader, provide a title for your images (or select the checkbox), and add a default description &/or keywords.

You can either browse for images or just drag & drop onto the target.  They'll be queued for upload, when finished a continue option with an "Edit uploaded files" button will appear at the bottom.  On that page you can tweak the individual titles &/or details as need be.
