Look into new FileNotFoundException error message

[FuzzyCrafter]

When copying in files from another project into the Babel repository to use Babel functions, I named them incorrectly with dashes in the file name instead of underscores. This message appeared in REPL when I tried to require one:

Execution error (FileNotFoundException) at babel.middleware/eval1121 (form-init16436014940846792569.clj:1).
Could not locate check/number_guess__init.class, check/number_guess.clj or check/number_guess.cljc on classpath. Please check that namespaces with dashes use underscores in the Clojure file name.

In Babel, the FileNotFoundException gets replaced with "The system was looking for a class .class or a file .clj, but neither one was found."

Perhaps the Babel error should be updated to include the suggestion from the new Clojure error message? Either way, this should be investigated.
