Initial commit of plugins consolidated to single "UnRAID" GitHub repo.  Plugin code amended to download supporting image files from external Dropbox share.  In the case of other supporting files eg. read_me.txt for SSH plugin or beets.sh for Beets plugin, these files have been added to the plugins themselves to be created during plugin install.  Lastly, where plugins also maintain the application versioning eg. NZBGet & Dropbox, these plugins have been altered to check versioning files now located on Dropbox share.
