fix that the GPU name is printed before the name is querried from OpenCL

The cpu miner backend uses the wrong ranges of nonces instead of using `[startNonce,startNonce + nonce_chunk)`
(startNonce,startNonce + nonce_chunk]` is used. This will results in an overlap with nonces used by the gpu back-ends.

revert the change that the OpenCl function `rotate` is used instead of `SKEIN_ROT`

- Eliminate modulus math (It runs slow inside microcode).
- Convert whatever the hell was going on into a rotate op. Like... Someone kinda reinvented the wheel in order to do a simple rotate.

reduce memory usage to 1GiB for NVIDIA devices with <=6 SMX

Ignore any affinity >=64 and throw a warning.

- if the intensity is zero than do not suggest a config
- remove the links to old issues

update VEGA names

bug was introduced with #67

- increase the L3 sanity check to 2GiB
- fix usage of byte instead of KB

Changed capitalization of "macOS"

Squashed the commit

remove warning `#pragma once in main file`

Occassionally the auto adjust doesn't find enough memory and the
intensity is detected too low and aligned to 0 with the compute units.
This patch fixes this situation by issuing a warning with a suggestion
to set environment vars and then ignoring the alignment to 0

- fix cuda9.1 compile (remove includ eof device_functions.hpp/ removed with cuda9.1)
- remove NVIDIA Volta gpus for MAC OSX

handle all error codes from the cuda api calls.

solve #440 thanks @true-datura

Makes casting more explicit.

When compiled with VS2017, the negative applied to the uint wait
time is ignored. Fixed by casting first.
