feature 2616: HTML5 upload (with plupload 2.1.2). First basic implementation. Needs customization.
Chunked upload + Drag & drop (no more Flash) use a new specific API method pwg.images.upload git-svn-id: http://piwigo.org/svn/trunk@28545 68402e56-0260-453c-a942-63ccdbb3a9ee

+/**
+jQuery based implementation of the Plupload API - multi-runtime file uploading API.
+
+To use the widget you must include _jQuery_. It is not meant to be extended in any way and is provided to be
+used as it is.
+
+@example
+ <!-- Instantiating: -->
+ <div id="uploader">
+ <p>Your browser doesn't have Flash, Silverlight or HTML5 support.</p>
+ </div>
+
+ <script>
+ $('#uploader').pluploadQueue({
+ url : '../upload.php',
+ filters : [
+ {title : "Image files", extensions : "jpg,gif,png"}
+ ],
+ rename: true,
+ flash_swf_url : '../../js/Moxie.swf',
+ silverlight_xap_url : '../../js/Moxie.xap',
+ });
+ </script>
+
+@example
+ // Retrieving a reference to plupload.Uploader object
+ var uploader = $('#uploader').pluploadQueue();
+
+ uploader.bind('FilesAdded', function() {
+
+ // Autostart
+ setTimeout(uploader.start, 1); // "detach" from the main thread
+ });
+
+@class pluploadQueue
+@constructor
+@param {Object} settings For detailed information about each option check documentation.
+ @param {String} settings.url URL of the server-side upload handler.
+ @param {Number|String} [settings.chunk_size=0] Chunk size in bytes to slice the file into. Shorcuts with b, kb, mb, gb, tb suffixes also supported. `e.g. 204800 or "204800b" or "200kb"`. By default - disabled.
+ @param {String} [settings.file_data_name="file"] Name for the file field in Multipart formated message.
+ @param {Array} [settings.filters=[]] Set of file type filters, each one defined by hash of title and extensions. `e.g. {title : "Image files", extensions : "jpg,jpeg,gif,png"}`. Dispatches `plupload.FILE_EXTENSION_ERROR`
+ @param {String} [settings.flash_swf_url] URL of the Flash swf.
+ @param {Object} [settings.headers] Custom headers to send with the upload. Hash of name/value pairs.
+ @param {Number|String} [settings.max_file_size] Maximum file size that the user can pick, in bytes. Optionally supports b, kb, mb, gb, tb suffixes. `e.g. "10mb" or "1gb"`. By default - not set. Dispatches `plupload.FILE_SIZE_ERROR`.
+ @param {Number} [settings.max_retries=0] How many times to retry the chunk or file, before triggering Error event.
+ @param {Boolean} [settings.multipart=true] Whether to send file and additional parameters as Multipart formated message.
+ @param {Object} [settings.multipart_params] Hash of key/value pairs to send with every file upload.
+ @param {Boolean} [settings.multi_selection=true] Enable ability to select multiple files at once in file dialog.
+ @param {Boolean} [settings.prevent_duplicates=false] Do not let duplicates into the queue. Dispatches `plupload.FILE_DUPLICATE_ERROR`.
+ @param {String|Object} [settings.required_features] Either comma-separated list or hash of required features that chosen runtime should absolutely possess.
+ @param {Object} [settings.resize] Enable resizng of images on client-side. Applies to `image/jpeg` and `image/png` only. `e.g. {width : 200, height : 200, quality : 90, crop: true}`
+ @param {Number} [settings.resize.width] If image is bigger, it will be resized.
+ @param {Number} [settings.resize.height] If image is bigger, it will be resized.
+ @param {Number} [settings.resize.quality=90] Compression quality for jpegs (1-100).
+ @param {Boolean} [settings.resize.crop=false] Whether to crop images to exact dimensions. By default they will be resized proportionally.
+ @param {String} [settings.runtimes="html5,flash,silverlight,html4"] Comma separated list of runtimes, that Plupload will try in turn, moving to the next if previous fails.
+ @param {String} [settings.silverlight_xap_url] URL of the Silverlight xap.
+ @param {Boolean} [settings.unique_names=false] If true will generate unique filenames for uploaded files.
+
+ @param {Boolean} [settings.dragdrop=true] Enable ability to add file to the queue by drag'n'dropping them from the desktop.
