Cleaned up local repository

Cleaned up the huge mess I created, pushing back to catch everything up.
Redoing crypto plugin as main component instead of plugin.
Likely compressing existing project files on first crypto run,
then storing the encrypted archive blob in the project directory.
When pappy started again, it will see the encrypted blob, extract
files to working directory, do all of its work in that directory,
then exit the directory, and clean up all files. A lot of work, but
worth the end result!
