New version 2.2.3 release.

These are the modification - I have had to modify some of the core functions so that they become OS independent. So please check if this version works as expected. If not please reinstall 2.2.2 and report the issues to me so that I can fix them.

- Fixed a file sharing bug.
- Changed Thread-functions to be OS independent.
- Changed File I/O to be OS independent.
- Fixed a the time-interval for updatechecks.
- Shows information how long the Merkle Tree generation took (MTP only).
- Shows the current mining block if the information was available in mining notify.
- Shows optimized grid- and blocksize that is used for the Kernel.
- Add power usage information into API information. Requires Awesome Miner Version 6.3.4 or later.
- ProgPoW: Show when a new algo is created (New Epoch for BCI, otherwise after 50 block).
- ProgPoW: Calculate optimized blocksize for each new algo.
- ProgPoW: Add version used by Zano (Cuda 10.1 only - older cuda versions will follow soon).

Happy mining!
