Update to clang-format-5 and reformat the codebase 

Since we have put PeakShape in Geometry, SpecialCoordinateSystem must be moved to the Kernel package out of API.

IntegratePeaksMD v1 and v2 write out integrated peak info in the form of PeakShape

PeakShapeSpherical adapted to write out background outer radius and background inner radius as well as the peak radius. Factories also updated for this, unit tests added to and updated for this.

I got a little worried that someone may change the integer values agaist the enum entries of SpecialCoordinateSystem. So I put in place a unit test to sanity check those.

Because json.h is exporting types with dll_export set, which in-turn export types without dll_export set, I have had to disable those specific warnings. We do not have control of this third-party component, so cannot fix the headers.

Add an type for representing no peak shape (position only). Also refactor to move common working code into a PeakShapeBase class. This is useful for serialization to ensure that there are no two diverging methods for serializing types of PeakShape.
