A quick glance over the code (aes.js:485..486) suggests that the first 
block of "ciphertext" produced by rijndaelEncrypt() is the IV. So in 
order to decrypt this data it should suffice to take the first block of 
"ciphertext", set it as IV, and decrypt the remaining blocks. Haven't 
tested it, though.
