idea: "custom" mode for "location" in config

[ArtOfLuxis]

if you set the type to custom you can choose the coordinates by yourself instead of spawn

something like this:

join: location: CUSTOM

coordinates: x: 0.0 y: 105.0 z: 0.0

hide-inventory-safe: true

or this:

... coordinates:

• 0.0
• 105.0
• 0.0 ...

so it can be either a list or just a pair with Doubles for coordinates

github kinda makes the text strange but i think its easy to understand what i meant
