Version update for 0.8 development
Remove passwordLen from EncFSPBKDF2Provider.doPBKDF2()
Fix unicode issue in EncFSCrypto.getBytesForBlockAlgorithm()

When computing padding length for chainIv computation we were directly
using the string length as byte length. Unicode files have different
byte length than their string lengths, resulting in incorrect chainIv
being computed and throwing EncFSChecksumException on valid files. Fix
uses the correct byte count and works fine for unicode file names.
