YafaRay plugin; update roadmap and change list

[povmaniac]

I have separated the project in several files, to be able to be work better at concrete 'areas'.
I even am looking for the best way of doing this, due to my little knowledge of Erlang.

Btw .. oort. I said that it would help with the exporter, but I did not say that it would do all the work..
I want to see as you do a fork of the repository and, he starts sending ' pull request '
