#29Run-time errors in typedValue

29 typedValue (in Parser.hs) has two conditions that result in run-time errors. For testing higher-order functions, it would be good to be able to type in the name of a function in the global environment, but we don't have access to the environment here, do we? Also in case of failure, it should fail with an error message but not crash sifflet.

O: 2012 Jun 15 R: gdw P: high Crashes program. C: 2012 June 21 -- fixed.
