Tutorial: Adding unofficial LDraw parts to MLCad

[Santeri Piippo]

I disagree with the entire notion of installing the complete unofficial parts "library". It's not a library, rather a collection of WIP parts on the parts tracker. The website page for the unofficial parts which you even took a screenshot of goes out of its way to mention first off that these parts are liable to change without warning and it's generally much better to get them one-by-one. I don't think we want to encourage the ultimately reckless behavior of getting all the unofficial parts. We'll just get users complaining that their models break because they used held parts...
