Huge performance improvement

I’ve just submitted code to svn that brings a long-awaited feature to 0.2.5: Using SSE2 to compute the Key Confirmation Key and the Message Integrity Code when attacking a EAPOL-handshake. Long story short: The commands attack_cowpatty and attack_db (aka “cracking the password via precomputed tables“) are MUCH faster than before. Using Pyrit 0.2.5-svn r208, my MacBook Pro 2×2.5Ghz and a precomputed database I got around 300.000 keys per second. With r209 I get around 1.000.000 keys per second; we are more than 3x as fast as before.

I’ve also fixed a stupid performance regression and improved the performance of the storage-backend. All in all you should see some flying wheels with r209.
