Add /logging command and config to enable/disable debug logging

[uniformization]

You can now enable debug logging by running /playit logging enable and disable debug logging by using /playit logging disable. The plugin now uses SLF4J for logging.

Fixes #21

This looks awesome! Thank you for putting it together. I'll plan on testing it locally tomorrow and if all looks good merging and pushing out a new release.

Really close

most servers will not print debug logs, I think we should use LOGGER.info here so the log statements are printed. If hasDebugLogging is set to false we can use LOGGER.debug and it will use the server's overall settings.

I don't really know if Spigot has it's own way to access the spigot.yml or server.properties file yet. Should I switch back to using Java's logger or write something to read the files directly?

I think we just do

if (PlayitBukkit.hasDebugLogging()) {
   LOGGER.info("[" + className + "] " + format, data);
} else {
   LOGGER.debug("[" + className + "] " + format, data);
}

if (PlayitBukkit.hasDebugLogging()) {

}

Oh, if I were to use that approach, I would have to switch to Java's logger. I already wrote something to use the spigot.yml file directly. Ill just push what I have right now using SLF4J and please let me know if its good or if I should switch to Java's logger!

LOGGER.debug also strangely doesnt work, despite isDebugEnabled() in the logger being true.
