[Feature Request] Customise hover over for player count

[TomLewis]

Is your feature request related to a problem? Please describe.
Once #91 is fixed.

Allow us to customize what is shown when hovering over player counts

Describe the solution you'd like
Allow us to specify exactly what we want when hovering over player counts and placeholders like %random_player% %online@server% %online@world%.

For example in ServerListPlus I was able to use &a%random_players@survival,3|, % which showed 3 random players online to that specific server.

Here is what I used to use:

  Players:
    Hover:
    - |-
      &eAhoy scallywag, get ye booty on PirateCrarft!
      
        - &aSurvival: &e%online@survival%/100 players online
        - &aCreative: &e%online@creative%/50 players online
        - &aTest: &e%online@test%/50 players online

      &a%random_players@survival,3|, %

      &aJoin now and play together with %random_player% ...
