Skip clitics for stem name stuff & fix sp to _
Skip clitics for stem name stuff & fix sp to _

Clitics were causing problems in the output of final allomorph info. Just skip them since they won't have stem names or inflection classes.
Also fix bug where we want to convert spaces to underscores but the function that converts periods to underscores was called instead.
