bulk_file_rename(): prefix is now added to the start of file names and suffix to the end (they were swapped), once per file. It no longer changes the working directory, and will not overwrite an existing file.
plotscat(): bayes_factor now works for all plot types, and BF= only appears in the title if it was requested. condcols is now used. Results for group splits are named sigyz1.* and sigyz2.* (sigz.p and sigz.bf are kept for group 1).
