1.0.8 is out.

- work timeout (fails over when working on the same block too long)
- send stale shares (potential poolside sharerate increase up to 1%)
- shorter log output (mostly fits 1 line on fixed-width win console)
- counting shares [A0+0:R0+0:F0] (A= accepted+accepted stales, R=rejected+rejected stales, F= fails)
- longer default hashrate update interval when using stratum
- cleaned up loads of Linux build warnings. not all I'm afraid.
- fixed --opencl-device bug
- i may have accidentally fixed the DAG switch crashes. let me know if it still crashes on next epoch change.

what's up for 1.0.9?

- investigate GPU load drops.
- Pascal support

Of course i want dual-mining and on-GPU DAG building too, but I don't have much time...
