Title: sel returns dataset when :rows :all specified

Before the fix a simple list was returned for datasets with a single row
when `:cols :all :rows :all` was used with `incanter.core/sel`. Although `sel` is supposed to return
simple lists only when at least one of the query params `:rows`and `:cols`
is an atomic object (index or name).

Fixes issue #235
