Outdated resource list in "Creating Your Type’s DNA"

[ahangarha]

From the resources provided in Creating Your Type’s DNA, it seems only one of them (JAF Generator) works. We might need to consider removing the others and add new one.

Lines 76 to 79 in efdbd88

I don't have experience this field so I cannot provide any new list.

There are many issues about dead links. Time for a purge and fix. Preferably links that can stand-up to time.

we better to reply on Free Software solutions so that even if their development stops, one can revive them. They (almost) never die.

If I find any resources, I will list here.

...sections 1...5 should be resolved now.
...sections 6...32 yet to go.
This will eventually close several issues to dead/wrong links.
