Adding additional mod support

[ironchefpython]

I looked through the project, and I didn't see a list of mods that get published to https://factorio.rotol.me/

I would love to be able to submit a pull request that adds an entry to a list of mods to display on the website, and if accepted would rebuild the web page to add those mod(s)

The current process is:

• Generate mod/config packs locally using https://github.com/Murnto/Factorio-PackGen
• Push the generated pack files to the server
• Reload the server

This isn't an ideal process, there would be a number of things to consider for an automated system:

• Proper sandboxing/isolation of Lua within Factorio-PackGen
• Factorio-PackGen is liable to break due to quirks in certain mods (these are generally trivial to fix by hand, but automatically handling it likely won't be)

More minor:

• Obtaining the mod files
  • Hardcoded direct links to zips?
  • Pulling from https://mods.factorio.com/?
• Handling changed mod dependencies from version to version

You're more than welcome to submit a PR :)
