missing header in refactor/spatlib

[avilleret]

since refactor/spatlib build fails on Travis, I try to fix it by updating CMakeLists.txt according to the recent SpatLib.yml changes
But I realized that some sources and headers are missing in the repo.
Among others :

source/TTSpatBase.cpp
source/TTSpatBaseRenderer.cpp
source/TTSpatDBAPRenderer.cpp
includes/TTSpatBaseRenderer.h
...

The refactor/spatlib branch is still in flux, and will not compile anywhere until me and Jasch are done tidying it up. By then we'll merge into dev and delete the branch.

I know, but I can't see a red mark on my dash board :-)

btw to be safely merged, it should build on Travis first.
