Title: removed confusing error message when multiple handlers fail

when configman tries to find a handler for an configuration value source, it iterates through all the candidate handlers. The handlers are too chatty and raise exceptions saying, for example, that the json module can't handle an ini file.

This change makes them decline silently rather than announcing it. This makes for friendlier error messages when a given handler reports a legitimate error.
