[5.5.0] History command

[archv]

My friends and I wanted to keep the history of played songs in chat as 'Now playing' message keeps removed or updated. Basically it is the same command from #192, but with another name.

/history command is introduced: it prints the same embed as 'Now playing', but with 'Played track' header on every handleTrackStart event.

I have also added defaultPlayerValues to config.js:

defaultPlayerValues: {
  twentyFourSeven: false,
  autoLeave: false,
  autoPause: true,
  autoQueue: false,
  history: false,
}

These values are then applied in players' constructors.

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes
• I know how to update typings and have done so, or typings don't need updating
• This PR changes the library's interface (methods or parameters added)

@BioCla do we set the version to 5.5.0 or 5.4.3?
