Integrated new Algos (#224)

- Added XLT v5/9 with autodetect(algo: "cryptonight", variant: "xtl" (autodetect), "xtlv9" (force v9))
- Added cn-lite variant UPX/uPlexa (algo: "cryptonight-lite", variant "upx")
- Added force-pow-variant parameter to force usage of the variant from the config and skip parsing of pow/variant from job/pool
