AJAX file uploader

[Joshas]

Here's the alternative file uploader for GetSimple. I used Valums AJAX file uploader ( http://valums.com/ajax-upload/ ). Main features include translatable text (not available in Valums script), Flash player is not required and it has a fallback upload form to work on browsers with disabled JavaScript. There are some issues, though. Image thumbnails are not generated (can be easily fixed by copying some code from original upload script), default file size limit is 10MB (could be changed, I think) and some minor styling issues.
Please test it and tell me what you think. It works on latest GetSimple revision r243, might need some hacking to work on others. Maybe one day it could become the default file uploader for GetSimple?
