I ran into weird issues testing this noise profile out with the
custom-library.db-preset, hence, the patch.

The profile tarball (tar.xz) is available here:
https://docs.google.com/file/d/0BycbxEgslvcpNGRpVEhPcEtxbk0/edit

Important Safety Tip I discovered while putting this together: Make
sure that the output profile setting under "export
selected"->"profile" is set to "image settings". I had it set to sRGB
and it took me *way* too long to figure out why noise profiling was so
messed up. :F

Perhaps this could be ameliorated by extending darktable-cli to allow
overriding the export settings on the command line (so that
gen-profile.sh could ensure others don't get hung up by this)?

Here are some benchmark results...
