##
- Charset: Add additional DES charsets with corrected parity
- OpenCL Buffers: Do not allocate memory for amplifiers for fast hashes, it's simply not needed
- OpenCL Kernels: Improved performance of SHA-3 Kernel (keccak) by hardcoding the 0x80 stopbit
- OpenCL Kernels: Move from ld.global.v4.u32 to ld.const.v4.u32 in _a3 kernels
- OpenCL Kernels: Replace bitwise swaps with rotate() versions for AMD
