Bumped version to 1.2.

Added `/balance` and `/pay` commands and a config option to enable them.

Added safeIs method to Config to match values without case sensitivity.

Added getCurrencyText method to Config to generate a formatted string from a currency amount.

Value 'format' from config file now supports amount-name replacement.
