[Enhancement] Arena "modes"

[SXRWahrheit]

Currently to have the same physical arena use multiple different sets of options, you must create separate virtual arenas. This has several downsides - concerns about conflicts between the virtual arenas running at the same time, separate join commands, etc.

I suggest arenas have a new categorical option - tentatively named "modes" - which allow creating discrete groups of settings that do not overlap. So, I could have one physical arena with two different modes.

The reason I ask for this, personally, is because my players want to have a choice between using their own items and using my pre-defined kits. Obviously it would be ideal to avoid players accidentally mixing the kits and personal items! I can currently achieve this using multiple "arenas," but doing so is undesirable for multiple reasons. Having a "mode" option load the relevant presets in the same "arena" would avoid this overlap and improve customization.

Can be complexe because one arena = one file.
We can simply refacto region protection to disable it when player is playing another arena and we must disable the other arena during the first arena fight (to not having 2 fights on the same arena at the same time 😆)
This second point is more technique: how detect arena which "physically" use the same battleground.

it's not easy ^^'

I don't think it's that complex, or at least that it's a power-user feature where the complexity is an accepted function of the usability.

Just stick each full mode config under its own key in the arena file. Same as usual but with an extra layer (and increased file size for modes users, obviously).
