Log missing Vault/economy plugin during parsing of money things.

Changes the "Vault was not found" message in Vault setup to INFO instead of WARNING, because this configuration isn't actually necessarily a warning sign. Parsing a money thing with no economy is, however. MoneyThingParser logs at ERROR level if Vault or an economy plugin isn't found, but a money thing is parsed.
