Serving index.htm and index.xml files

[khanlou]

I know this repo hasn't been updated in a while, but would you open to adding index.htm and index.xml files to the index directive of the erb template?

Change from

index index.html;

to

index index.html index.htm index.xml;

My jekyll site serves the xml feed at $SITE/feed and so it doesn't know to serve index.xml as the index of that directory.

Happy to open a PR if you're open to it.

Sounds good! Please make a PR.
