Adds more options and info regarding local web servers

I started adding to the doc, but I think perhaps some of this should be trimmed down or turned into its own section since it's just a response to the question about jQuery being loaded via protocol-relative URI syntax.

**Trim down** 
Perhaps we should remove the more complicated servers and stacks all together since they're far outside the scope of the question. I think this would make the document look fine..

**Turn into its own section**
On the other hand, having a list of some common servers and stacks might be useful to some folks so perhaps we should simply add another section for it somewhere in the docs (in misc.md, I would think) and then link to it from that question.


Let me know what you think and I'll go ahead and make the changes unless someone else wants to do it.
@QWp6t same here, we should probably just go with 8080.
