Upgraded fast to latest version and implemented manual seed point

Only tested on ubuntu 16.04

This gives errors on creating the CustusX installer on Linux and Mac. The variable ${FAST_SOURCE_DIR}
which was used to copy files into the installer in the Airways plugin is now empty. Can you look into that?

On Windows there is a build error for many files because of some MP flag I think. Can you look into that?
E.g.:
[shell ###] FAILED: CMakeFiles/FAST.dir/source/FAST/Algorithms/ImageSlicer/ImageSlicer.cpp.obj
...
-IC:\Qt\Qt5.6.0\5.6\msvc2015_64.\mkspecs\win32-msvc2015 /DWIN32 /D_WINDOWS /W3 /GR /EHsc /openmp ;/MP /MD /O2 /Ob2 /D NDEBUG /showIncludes /FoCMakeFiles\FAST.dir\source\FAST\Algorithms\ImageSlicer\ImageSlicer.cpp.obj
...
[shell ###] MP
[shell ###] c1xx: fatal error C1083: Cannot open source file: ';/MP': No such file or directory

There is a ; which should not be there. Try replacing
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}" "/MP")
with
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /MP")

in FAST/CMakeLists.txt. If that works on your system I will add the fix to FAST.

I have pushed a new commit to my upgrade-fast branch which should fix the ${FAST_SOURCE_DIR} issue. However since this PR has status merged, I don't think the commit will show in this PR. smistad@1dde3a2

I see you have opened a new PR.
Your suggestion fixed the first problem with the MP flag, but I got this error then:
C:\dev\cx\FAST\FAST\source\FAST\Algorithms\IterativeClosestPoint\IterativeClosestPoint.cpp(79): error C3016: 'b': index variable in OpenMP 'for' statement must have signed integral type
Setting the first looping index after the pragma to int madde it compile:
#pragma omp parallel for
for(uint b = 0; b < B.cols(); ++b) {
==>
#pragma omp parallel for
for(int b = 0; b < B.cols(); ++b) {
