Subject: Lem: Make generated assertion messages look nicer in prover output

Add a new short_loc_to_string function that produces just the file and line number as
a single line. loc_to_string adds a bunch of terminal color codes and other formatting
designed for producing pretty error-messages in the terminal, which isn't ideal when
the string appears in prover output as part of an assert statement. This is should be
purely an aesthetic change.
