Accomodations to be able to transcribe RWR files.

[marybeckman]

In order to be able to use the same procedure
count_nwr_wordlist_structures()
code to count the 24 (or 26?) real words that are matched with nonwords for the lexicality effect are transcribed, we need to make sure that the RWR wordlist structures are set up in a way. Maybe that can be done just by making sure that the TargetStructure column is in the same place and includes "CV" only for those 24 (or 26?) rows. Or maybe it will be easier to modify the procedure in the transcription file. Keep in mind as we (re)build the RWR wordlists for TP2.
