Fix odd bug, where SXP.read_file and SXP.read_url were only retur…

…ning the first expression read. This was likely an over-simplification for when the file contained only a single expression, and we didn't want to see this contained within an array.

@bendiken, if something relies on the old behavior, we could return the first expression if the result contains only a single expression, but that would seem to be less consistent behavior.

Fixes #14
