missing files in USER-packages build observation

Christian:

I went ahead and experimented with building the USER packages and found that the following 3 packages need more files before successfully completing.

In particular, the USER-CUDA script didn't seem to grab all the necessary files from the USER-CUDA area, when setting the USER-CUDA install option, much to my surprise.

Anyways here they are:

USER-MISC needs:
./MANYBODY/pair_eam_alloy.h
./MANYBODY/pair_eam_alloy.cpp
./MANYBODY/pair_eam.h
./MANYBODY/pair_eam.cpp

USER-SPH needs:
pair_lj_cut_coul_long.h
pair_lj_cut_coul_long.cpp

USER-CUDA needs:
fft3d.cpp
fft3d_cuda.cpp
fft3d_cuda.h
fft3d.h
fft3d_wrap.cpp
fft3d_wrap_cuda.cpp
fft3d_wrap_cuda.h
fft3d_wrap.h
pppm.cpp
pppm_cuda.h
pppm.h
remap.cpp
remap.h
remap_wrap.cpp
remap_wrap.h

(sorry about leaving out the source reference for the last 2 user packages)

This should help. The other USER packages built just fine.
