@go command
- Alternative @go command. Allows for unlimited aliasing, as well as level and group restrictions for each destination. Additional options to add a delay, prevent use when dead, and charge per use are available; default cost is defined with '.cost', but this parameter can be set manually with 'go()'. These extra features are disabled by default.
- Special thanks to jTynne for coming up with the original concept.

Compatibility:
- Optimised for Hercules emulators.
