unserializer: improved

I spent a few min­utes improv­ing the unse­ri­al­izer tool today. So whats new?

1. You can choose to view out­put as var_dump or var_export, in addi­tion to the print_r option that was already there.
2. Added jQuery:
   1. Uses Ajax instead of doing a nor­mal form submission.
   2. Shows an Ajax load­ing icon when you sub­mit the form, and the out­put box flashes yel­low when it is updated.
   3. Over­rode press­ing the “enter” key to always sub­mit the form. In rare cir­cum­stances this may be annoy­ing, but I think in gen­eral it is a good feature.
3. Added some styl­ized text to the top, and added a copy­right at the bot­tom. Per­haps I’ll clean my code up some­time and release it, but for now it is copyrighted.

Any­ways, I hope oth­ers find it as use­ful as I have!
