#71 Add support for direction

[Alexey Guseynov]

I would like to see shooting directions on map. I've implemented this functionality, you can look, how it works here:

Now I just want to share this code with others. It still needs some more work and may be won't suit everybody out of the box, but at least it works. I've written additional information about this pathc here:

Thank you for the patch. There's an existing feature request for this (see 1412304). Due to my lack of time and the significant changes this patch makes, I likely won't be able to incorporate these changes into the module, but with the patch, at least someone else can use your work.
