/**
* mmSWFUpload 0.7.1 Revision 3 by Jacob Roberts, January 2007, linebyline.blogspot.com
*
* + Fixed a bug in the upload.swf that prevented further file processing after an error is returned.
* + Added uploadLimit variable. Only complete uploads are counted. Once the limit is reached the flash
* movie will not upload any more files. (The ability to select or queue many files is not affected
* by the upload limit)
* + Added cancelQueue and cancelUpload methods.
* + Added ID property to the FileObj in the upload.swf
* + Added Upload and Queue settings
* + Added methods for generating the flash HTML and inserting it into the DOM.
* - Removed SWFObject
* + Updated the upload.swf and added the "flashReady" event. This will only call back
* for Flash 8 and above. With this we don't need a flash version detect script.
* The script initializes the Flash then waits for the Callback to init the UI.
* + Added seperate ui_target, degraded_target, create_ui settings. This allows fine control
* over what parts of the GUI the script displays and hides
*
* + Changed from a Static Class to an Instance (changed code/class structure)
* + Added "flash_version" setting. When set to zero the version check is skipped
* + Added Debug Console. The Instance class can't do document.write.
* = De-obfuscated SWFObject a bit
* - Removed standalone mode.
* + Added "ui_target" setting. When non-blank the link is added.
* + Added "flash_target" setting. When blank the flash is appended to the <body> tag
* = This fixes ASP.Net not allowing the flash to be added to the Form
* + Added error checking to the callSWF method
*
