v0.2.0

A bunch of improvements to move console to «ultimate» state a little closer.

What's:

• console.colors is an instance of cli-color now.
• console's .log, .info, .warn, .error are customizable:
  • prefixes
  • colors
  • output streams: stdout or stderr

var console = Console(null, null, {
  styling: {
    log: {
      prefix: ' * ',
      color: console.colors.green,
      stream: 'stdout' // can be 'stderr' or 'stdout'
    }
  }
});

• console.clear: clears output streams.
• console.count: counts own calls.
• console.debug: simple alias of .log.
• feature gates for .debug, .count, .clear:

var console = Console(null, null, {
  styling: true,

  count: true,
  clear: true
  // debug: false
});
