Configure index

[nickcarenza]

Can there be an option to set the default served file to something other than index.md? I would like to use docserver to serve an entire project and would like to point it at README.md since that is what most people consider to be the documentation entry point.

This could be an option passed to the constructor. It could take an array of basenames to look for (['index', 'default', 'README']). These would be tried in order, by appending the target extensions (default is ['.md', '.mdown']). First one found wins.
