Subject: key-length for mask mode.

Hi Alexander,

I have introduced a few changes to raw-md5-kernel. Now we can achieve
nearly 2700Mc/s with around 12k loaded hashes.

Loaded 12906 password hashes with no different salts (Raw-MD5-opencl [MD5
OpenCL (inefficient, development use only)])
Press 'q' or Ctrl-C to abort, almost any other key for status
Using kernel md5_ccc...

More optimizations are possible if we could limit the key length to 16.
Current key length limit of 55 seems to be unnecessary. This should free up
some more registers and allow me to introduce few more bitmpas.
