Add feature to automatically download levels from Mods repository

[thekovic]

The current community archive of mods/levels is at https://github.com/Jones3D-The-Infernal-Engine/Mods . This is not the most user-friendly to download from. Indy3DModInstaller could be extended to scan this repository and allow the user to select and automatically download a mod from there.

In Powershell this would be

$download_location = "C:\Temp_Mod_Folder"
$download_mod_temp_file = $download_location + "\sedlevel.zip"

Invoke-WebRequest -Uri https://github.com/Jones3D-The-Infernal-Engine/Mods/archive/refs/heads/main.zip -OutFile $download_mod_temp_file

Expand-Archive -Path $download_mod_temp_file -Out $download_location

# DO YOUR MOD INSTALL MAGIC HERE.

I'd also write some logic then to disable that feature if the tool sees that it's offline. You don't want to throw errors to the user like not connected errors from Windows and such. Since those are too technical. What I usually do is write a function to check if we are online and then disable or enable the buttons if we are online or offline and adjust my error messages to something more human readable.

This is how I did the downloading and extraction of the tools in my tool... those tools you include in your install.
