Don't discard deprecation/unchecked warnings re...

Don't discard deprecation/unchecked warnings regardless of settings.

Changed warnings code to accumulate them rather than thoughtlessly
discarding them and issuing its well-known taunt. In the repl you can
take advantage of this with the :warnings command, which will show the
suppressed warnings from the last line which had any. Be advised that at
the moment it has some issues: unchecked warnings aren't making it out,
and near repl startup neither are deprecation warnings, so don't open a
bunch of tickets please.
