Port of fileshare in D7 and D6

Hi,
I've been secretly continuing to use this module, that I personnaly rewrote (before seeing the patch proposed in this issue) in D6, and I have been using it for a few years since.
Through the process of migrating my company's website in D7, I've decided to adapt it, once again.
I've never thought of bringing that to other potential users of this project, mainly because of the security issue that I didn't really try to fix.

So I have a version, fully D7 compatible, that features :
- Integration with the new File api in D7
- jQuery for client javascript
- Drag'n Drop Feature (that you can enable or not)
- Slightly redesigned

I also have a D6 version, fully functionnal, but without the previously mentionned features (it's mostly a direct port of the D5 version).

If you are interrested, or if you wish to review the code, test it, whatever, just let me know.

I'd be glad to contribute to the Drupal community, but I don't really know how/where to start.

Cheers !
