Online word synchronization

[Epicpkmn11]

This makes work more like the new method of the official version, with words used by a separate index which is fetched from the internet. I'm not super happy to have to make this change as I think offline play is very important (being as DS's don't have data connections lol), but by using a cache it should only need weekly or so updates. My #1 design goal with this is to match the official daily word, so something sustainable is important.

TODO:

• [x] Fetch words from internet
  • Using special purpose API from http://wordle.xn--rck9c.xn--tckwe
  • [ ] WPA support (unlikely)
• [x] Integrate into GUI
  • [x] Button to fetch words
  • [x] Prevent play and prompt for update when out
    • Infinite mode will still work
• [x] Ensure old mods still work

I'm also revamping the GUI code slightly since this is just a rather convenient time to do so, even if overusing this branch a little.

• [x] Popup message now has its own layer
  • [x] Popup on trying to toggle hard mode when playing
  • [ ] Popup on QR when playing
• [x] Main menu icons are now movable sprites

Getting quite close, main thing left is the whole prevent playing beyond the end thing and probably a bunch of backward compatibility fixes

I think this is good now, if anyone wants to test please let me know any issues

barring issues and with a bit more thorough testing expect a new release soon
