Make include-what-you-use happy with some files in source/tools/atlas and fix what needs to be fixed. Add "source" to include path for AtlasUI target to allow for absolute includes. In the future all but one should be removed. Drop check for at least boost 1.40. Ref: #8086 Signed-off-by: Ralph Sennhauser <ralph.sennhauser@gmail.com>
