Fixes This class is not key value coding-compliant for the key "keyPath"

Since "Key Path" is the header for run time attributes, my guess is that
this was a click misfire so long ago. I'm not clear if this was ever
causing a crash or just a warning, but we don't want the noise.

Fix "Unbalanced calls to begin/end appearance transitions"

You should not segue while animations are in progress. I'm not sure if
this was causing intermittent crashes or just the warning.
