Minor feature request: config option to exclude symbolic links about ngx-fancyindex

[aperezdc]

This seems like an interesting feature to have, I can think of a couple of uses myself 👍
I'll be adding a configuration flag for this.

@DarkHelmet433: I have pushed a commit that implements filtering of symbolic links as suggested, and that can be toggled using a configuration directive. It works for me, but I am still going to wait a little while before making the next release, so feel free to check it out the feature building from Git and comment in case the feature does not work for you. Ah, and thanks again for the suggestion 💡

I checked it out from git, but it segfaults while parsing. One of the followup commits created a null pointer dereference. I've attached a fix as a pull request. #28 I believe.

And again, thanks for taking the time to work on this!
