- Fixed Method Returns for VintagePerms Abstraction

VintagePerms is Set to Possibly be Removed for Abstraction due to being Unnecessary as VintagePerms already hooks into VintageVault and will more than likely just be annoying to keep updating VintageVault for changes in VintagePerms. VintagePerms is still a new and ever changing plugin.

- Removed Unnecessary Methods (I previously Added)
- Updated GroupManager Methods
- Updated VintagePerms Methods
- Added Extra Support for PermissionsEx to Include New Methods

As the homepage says, this is fully replacing the old VintageVault plugin with a Custom Vault version I've created.

Main Changes:
- Multi-Currency Support
- VaultUnlocked Support
- CMI Plugin Support
- Extra Permissions Plugin methods for Develpoers

Works with 1.13, have fun!
