Not enough memory warning screen

[me-nx]

Follow-up on #65.

Added a warning screen shown on startup if JVM's max memory (-Xmx) is below a set threshold.

fyi @maskersss @Crystal15118

This looks pretty good, I have a couple things I would like changed though:

• I'd prefer if the warning screen was shown when actually starting a session rather than on startup, since thats when the player actually decides to play with the settings they configured
  • imagine a player starting up seedqueue for the first time, setting their settings, playing without warning, then the next day they come back and suddenly there is a warning screen that wasnt there before
  • this would probably require a small change in architecture, where seedqueue is actually started when pressing gold boots rather than after one reset. i've wanted to make this change anyway, it just depends on making antiresourcereload synchronized.
• I think the warning screen should contain more information
  • in its current state players would probably only understand it if they already know about seedqueues ram requirements and how to change allocation, it should tell the user why they need to allocate more memory and that they could alternatively reduce their max queued seeds too (could even factor in how much memory is even available on the system, it doesnt really make sense to tell a player to allocate 10GB of ram if they only have 8GB available).
  • additionally a link to a new seedqueue wiki page could be considered

Makes sense, I've moved the warning to starting resetting. Idk if this injection point is ideal though, but seems to work fine?

I've added a mention of max queued seeds and a link to a non-existing wiki page, I have a stub here if you'd like to add it (although you'd have to update image links).

What should be the threshold if I were to change that? It probably doesn't make sense to recommend allocating 6 gb if they have 8 gb total, but idk that depends on a lot of factors.

I know maskers has some threshold calculation in pingus recommended_settings, probably best to just copy that, I'll ping him on discord

This will currently also show a warning for people who havent actually set up seedqueue but have a very low amount of allocated ram (iirc multimc defaults to 1GB). While this isnt inherently bad, the warning screen doesnt accurately tell the user whats going on, so it would probably be easiest to just disable the check if config.maxCapacity is 0.

I'm also a bit worried that the link may not be super obvious, not everyone will hover the text since links arent very common in Minecrafts UI, I'd prefer just adding the link to the end.

Looks good to me, thank you for the PR :)
