D2k: Sandworms implementation

Using Mailaender's code as basis, this is my implementation of the sandworm behavior. It is still WIP, but you can get an idea of how it looks from the shellmap.

It looks like your editor may be overloading the function of the tab key to mean "line things up with the next `.`".
One extra tab character should be lining up the `.Except` and `.Where` with the `return false` further down.
