Bill Somerville 924e20efa8 Add a sample download dialog and upload sub-system
Samples are  downloaded from a  web server, currently the  SF download
server.   The samples  are  stored in  the  source controlled  samples
directory and the CMake script  there builds a suitable directory tree
for upload to the web  server under samples/web containing the samples
hierarchy and the  generated JSON contents database  file. The samples
CMake script also  defines an 'upload-samples' target  that uses rsync
to efficiently upload  the samples and the  accompanying contents JSON
database file.

Any directory structure under the samples directory may be created, to
add a new sample file simply add  the file to source control and amend
the list of sample files (SAMPLE_FILES) in samples/CMakeLists.txt.
