Added more connection functionality, now accepts two optional parameters, console-output and requires-factions.

If you specify requires factions (your plugin), and FactionsBridge doesn't find Factions, an error will be thrown.
If you specify that your plugin doesn't require Factions and FactionsBridge doesn't find Factions, console-output (toggle), will be used to print or not print messages.

Thanks to Splodgebox#3490 for the idea.
