0.1.3

new features:

• !skipsong and !removesong (which are the same command) let channel ops stop a song from being played
• !volume lets channel ops set the volume
• you can blacklist videos in the config file so they never play

bug fixes:

• it shouldn't randomly skip songs as much (or at all, hopefully)
• better reporting of non-embeddable or non-viewable videos when they are requested instead of silently skipping them when they come up to play
