#890 Normalize Romanian ș and ț

[Ahasuerus]

Normalize Romanian ș and ț. Create a data conversion script to find all occurrences of ş and ţ in Romanian (and only Romanian) titles and pubs to ș and ț. Create a cleanup report to find new Romanian titles and pubs with these characters.

Cleanup report implemented in:

edit/cleanup_report.py 1.38
edit/isfdblib.py 1.154
nightly/nightly_update.py 1.159

Installed in r2016-087 on 2016-05-26. Keeping the FR open since we haven't created an automated conversion script yet. It's not clear whether we need one given the number of titles and pubs identified by the cleanup reports.

[Ahasuerus]

All affected titles/pubs have been corrected manually, so we no longer need a conversion script. Closing the FR.
