Make block unlocking dynamic for admins

I tested out the survival beta, and one problem that immediately came to mind was that of modded blocks won't be using it. Some mods might be to old and the creators might not update it, and even if they did, the way they do it might be very wonky. Personally I run some 100+ mods when I do my server.

An idea is that the block-unlocking could be made dynamic for the admin to setup in game? That would mean you could have any number of blocks and you could still get your little universe working as you want. Preferably a simple interface in the admin menues that allows you to to select a number of blocks on the left, and then have it be unlocked by one or more blocks on the right.

That would also mean you could create multiplayer PVP scenarios with 'treasure' you might need to acquire, if you have special modded blocks that require some new resources like unobtanium to craft. Lots of options to create gameplay if only the block-unlock chain was easily alterable instead of having to mod it from the start, which might be impossible in some cases.

I'm sure it could be made to work with mods like grind-to-learn which is also popular for creating gameplay.
