tenderlove/psych — Issue #41: Unclear exception for non-existing aliases

Merging in a non-existing aliased key simply raises `TypeError: can't convert nil into Hash`.

Psych.load "foo:
<<: *bar"

Given that this message is so generic, it makes debugging pretty tough. Something along the lines of `Psych::UnkownAlias` would be a huge time-saver.
