Merge with e190c52ab7861c68762aaa552f3dc0f59fe2e225 from default

This revision compiles and runs on Win7x64- but further evaluation is necessary.
There may be an issue with cmake step -After cmake I had to copy rtgui/version.h & config.h into out of source build /rtgui folder.
Additional notes:
- ImProcFunctions::hsv2rgb01   -> this likely need to be added to color.h & color.cc
- Use of array2D should be verified in NR code
- compilation warning for rtengine::RawImageSource::isWBProviderReady()
