Ensure that included files are actually included (#26)

This resolves an issue where an ignored file will supercede an explicit
include.

Example:

1. If `.distfiles` includes `/node_modules/clipboard/**/*.min.js`
2. If `.distignore` includes `/node_modules`, it will override the above

The fix is a `.distfiles` exists and has contents, `.distignore` is not
observed - because `.distfiles` a safelist of files with more
flexibility than `.distignore` in its syntax.
