Hi all.

I posted a 2014-02-18 release that will not barf when it finds a Maxwell. This doesn't mean that it was optimized for Maxwell (it wasn't!), but it runs.
Previously you had to force it to use either the T kernel (scrypt, scrypt-jane) or the K kernel (best for keccak) in order to run. Now it's selected
automatically instead of just crashing.

Also CTRL-C terminates the program much faster when mining on a stratum server. Same for the --time-limit option.

Oh, and Autotune does something on Keccak. I just don't think it's of much use  You still need to pass a large -L parameter because otherwise
the (unnecessarily allocated) scrypt scratchpad limits the maximum number of warps we can run this with.

Let me know if my changes broke anything else for you...
