Add a new permission flag to toggle snowfall, like you would for firespread

[jwkerr]

Description:

I made this pull request as in my experience many people dread making towns in snow due to the constant covering of your builds in snow. It takes a lot of time and maintenance to keep your town clean, I've seen some go to the extreme of placing thousands of iron bars at the highest Y level to prevent snowfall. I think it is fair to add the ability to toggle this for players, if lag is a concern server admins can force snowfall on or otherwise remove access to turning it off.

some things i know need to be looked at:

• i think plot perm hud might break, couldn't test it as my test server is folia but it might make it too big
• not sure if i'm misunderstanding something but afaik i made the default behaviour for towns that snowfall is on, however in my test server it was off, the config's default value is true though and the value displayed was how it functioned in game

Before I merge this I would like you to tell me what happens to all of the plots before this feature is added.

Does the town/resident/plot require their TownyPermission to include Snow in order to have snow fall?

Will this update mean that all of a sudden snow accumulates nowhere on the server until those towns, residents, plots have their snow enabled?

as I wrote in a previous comment, I noticed that it defaulted to false and I don't know how to change that

the property in the townypermission should probably get renamed to nosnow, and have the logic flipped. If this PR were to cause all of the snow to not function anywhere it would be disruptive.

As commented earlier this will have to get overhauled to work in the opposite manner, or we'll end up breaking snow everywhere on already-existing servers.

Also moved this off of the 0.101.1.0 milestone.
