Hello, a lot of people have requested me to add the ability to have the voucher pick a random command and a way of having chances on commands. This update adds those 2 features.

Random Commands:
Pick a random command from the list of commands. No chance system is in place it just picks a random one.

Chance Commands:
https://github.com/kicjow/Vouchers/wiki/Chance-System-Wiki

Examples:
https://github.com/kicjow/Vouchers/blob/master/Config.yml#L120-L168

The examples have been placed in the new default config which can be found here.
https://github.com/kicjow/Vouchers/blob/master/Config.ym

Added:
- New random and chance commands options.

Bug Fix:
- The whitelist and blacklist permissions were not working due to the path in code missing a step.
- Old MCUpdate class spitting out blank messages in the console.

Changes:
- Switched from the old SettingsManager class to my new FileManager class.
- Switched out the old MCUpdate class for its new MassiveStats class.
