Map downloading / Map Server

[Longor1996]

Add a new GUI that can download maps from a URL or a server holding a map-index.

This should be relatively easy: Paste in URL, download zip file, extract to map folder.

The map index is harder, cause it needs a server without a rate-limit, which requires money that none of the TC-Team has. This is no longer an issue. @Longor1996 has a webserver.

Steps to implement:

• Serverside (PHP):
  • Create database for all things TaleCraft.
  • Create table to hold all the maps.
    • What data should be stored per map?
      • Name, Author, Details
      • Map & TC version, Size
      • Thumbnail?
      • Screenshots?
      • Required extra mods?
  • Create endpoint to query the table.
  • Create frontend to upload maps.
• Clientside (Java):
  • Create a new GUIScreen.
  • Query endpoint for map downloads.
  • Somehow mark already downloaded maps.
  • Add GUIScreen to see all details of the map.
  • Make it possible to download maps in-game into a downloads directory.
  • Make it possible to delete downloaded maps from the downloads directory.
  • Make it possible to 'play' a map by copying&unpacking it from /downloads to /saves.

Due to me now having a webserver (reachable at https://longor.net) with unlimited bandwidth, this can actually be implemented.
