Easier config comes to CPU! Better hashing method selection.

This is my first collaborative CPU release with psychocrypt. Here are the highlights:

New features:

• Easier config - the miner will now suggest a config appropriate for your setup.
• Much better cmake build script - see readme for build options
• Better hashing method selection allowing more flexibility - want double hashing with prefetch without aes? No problem!
• Speed boost for miners that cannot configure large pages.

Fixes:

• Memory leak (thanks esfomeado!)
• Bug affecting systems with 32+ cpus on Windows (thanks malafaya!)

If you don't know if you need TLS support, go with -notls version.
