Fixed bug where --points argument was not processed (-p worked though).

Updated gitignore

VENDOR_INTEL -> DEVICE_VENDOR_INTEL

Fixed bug where incorrect results would be produced on AMD devices.

The problem is in the modular inversion (invModP() function of
secp2556k1.cl). There is section that is looped 20 times. Breaking
the loop into two loops fixes the issue. The exact cause is still
unkown, but it seems to be an issue in AMD's OpenCL compiler, as
this does not happen in the Mesa OpenCL compiler, or nVidia's
OpenCL compiler.

Update README.md

Merge branch 'master' of https://github.com/brichard19/BitCrack

Update README.md

Added warning about clBitCrack bugs on AMD/Intel devices

Fixed bug where clBitCrack was not obeying --stride option

Build support for CUDA 8.0 SDK

NVIDIA has removed support for 2.x devices in CUDA 9.
Adding this in case anyone wants to build for those devices. Will
try to keep it somewhat up to date.

1. Install CUDA 8.0 toolkit
2. Replace "9.2" in all .vxcproj files with "8.0"
3. Change all projects to use the VS2014 (v140) toolset

Embed OpenCL code into executable to external files aren't necessary

Added 'embedcl' tool which takes a text file and encodes it into a
C++ file and can be accessed with provided symbol.
