jsoncpp - 1,8..3 - Update to latest version. Split package into a run-time and developer package subce a DKK as a DLL is now included
libuv - 1.15.0 - New package required for cmake.
rhrash - 1.3.5 - New package required for cmake. Note that the makefile and some other things had to ported to MSYS (Cygwin is incidental). The patch I wrote should also work on MINGW (kill two birds with one stone).
