Cross-platform support (Win, MacOS, Linux)

Browse Source 
-All shell scripts have been removed and replaced with javascript equivalents which allows for better platform independence
-All scripts have been improved over the older shell scripts to be more functional and dynamic
-Updated all applicable cmds in the package.json to target the new js scripts + added the backup, restore and delete database functions to the list
-Removed the json and strip-json-comments-cli packages as they are no longer needed
-Added a new package realine-sync
-Updated cluster code with better Windows support when shutting down the explorer
-Backup and Restore scripts now use mongo's own encryption instead of tar.gz by default. Older tar.gz backups can still be restored as long as the tar.gz suffix is explicitly added
-Backup and Restore scripts now support connecting to remote database based on the mongo details in settings.json
-Updated README to include a new line for the 'platform independence' feature, updated script cmds and notes about certain steps being Linux only
