Two minor changes to CMakeLists.txt needed to compile the extension.
Merge branch 'master' of github.com:gsi-biomotion/slicer-dirqa
Changed extension name in CMakeLists.txt.

For some reason the extension didn't compile anymore because of whitespaces in the name.
Changed color of warped volume in False Color check.

CoolTint1 (Cyan) is the complementary color scale to WarmTint1 (Red).
When comparing perfectly matching images this gives a greyscale result.
