/**
* The `FileLoader` class is a wrapper which handles two file operations: loading the content of the file stored on
* the user's device into the memory and uploading the file to the server.
*
* There are two possible ways to crate a `FileLoader` instance: with a [Blob](https://developer.mozilla.org/en/docs/Web/API/Blob)
* (e.g. acquired from the {@link CKEDITOR.plugins.clipboard.dataTransfer#getFile} method) or with data as a Base64 string.
* Note that if the constructor gets the data as a Base64 string, there is no need to load the data, the data is already loaded.
*
* The `FileLoader` is created for a single load and upload process so if you abort the process,
* you need to create a new `FileLoader`.
*
* All process parameters are stored in public properties.
*
* `FileLoader` implements events so you can listen to them to react to changes. There are two types of events:
* events to notify the listeners about changes and an event that lets the listeners synchronize with current {@link #status}.
*
* The first group of events contains {@link #event-loading}, {@link #event-loaded}, {@link #event-uploading},
* {@link #event-uploaded}, {@link #event-error} and {@link #event-abort}. These events are called only once,
* when the {@link #status} changes.
*
* The second type is the {@link #event-update} event. It is fired every time the {@link #status} changes, the progress changes
* or the {@link #method-update} method is called. Is is created to synchronize the visual representation of the loader with
* its status. For example if the dialog window shows the upload progress, it should be refreshed on
* the {@link #event-update} listener. Then when the user closes and reopens this dialog, the {@link #method-update} method should
* be called to refresh the progress.
*
* Default request and response formats will work with CKFinder 2.4.3 and above. If you need a custom request
* or response handling you need to overwrite the default behavior using the {@link CKEDITOR.editor#fileUploadRequest} and
* {@link CKEDITOR.editor#fileUploadResponse} events. For more information see their documentation.
*
* To create a `FileLoader` instance, use the {@link CKEDITOR.fileTools.uploadRepository} class.
*
* Here is a simple `FileLoader` usage example:
*
* editor.on( 'paste', function( evt ) {
* for ( var i = 0; i < evt.data.dataTransfer.getFilesCount(); i++ ) {
* var file = evt.data.dataTransfer.getFile( i );
*
* if ( CKEDITOR.fileTools.isTypeSupported( file, /image\/png/ ) ) {
* var loader = editor.uploadRepository.create( file );
*
* loader.on( 'update', function() {
* document.getElementById( 'uploadProgress' ).innerHTML = loader.status;
* } );
*
* loader.on( 'error', function() {
* alert( 'Error!' );
* } );
*
* loader.loadAndUpload( 'http://upload.url/' );
*
* evt.data.dataValue += 'loading...'
* }
* }
* } );
*
* Note that `FileLoader` uses the native file API which is supported **since Internet Explorer 10**.
*
* @since 4.5
* @class CKEDITOR.fileTools.fileLoader
* @mixins CKEDITOR.event
* @constructor Creates an instance of the class and sets initial values for all properties.
* @param {CKEDITOR.editor} editor The editor instance. Used only to get language data.
* @param {Blob/String} fileOrData A [blob object](https://developer.mozilla.org/en/docs/Web/API/Blob) or a data
* string encoded with Base64.
* @param {String} [fileName] The file name. If not set and the second parameter is a file, then its name will be used.
* If not set and the second parameter is a Base64 data string, then the file name will be created based on
* the {@link CKEDITOR.config#fileTools_defaultFileName} option.
