Implement a new pool strategy, BALANCE, which monitors work performed per pool as a rolling average every 10 minutes to try and distribute work evenly over all the pools.
...
Do this by monitoring diff1 solutions to allow different difficulty target pools to be treated equally, along with solo mining.
Update the documentation to describe this strategy and more accurately describe the load-balance one.

Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this.
...
Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.

Use a pthread conditional that is broadcast whenever work restarts are required. Create a generic wait function waiting a specified time on that conditional that returns if the condition is met or a specified time passed to it has elapsed. Use this to do smarter polling in bitforce to abort work, queue more work, and check for results to minimise time spent working needlessly.
