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. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6308 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
