Automatic mods toml generation + dependencies

[Thodor12]

• Create a dependency block called modDependencies which contains 2 configurations: required and optional for adding required and optional mods as dependencies.
• Features a task that can automatically generate a neoforge.mods.toml based on a new set of fields that must be provided in the mod block.
• This task also utilizes the above modDependencies block to automatically write all the mod dependencies, including Minecraft and Neoforge, to the neoforge.mods.toml.
