shorten 6.x-1.12

This is mostly a bugfix release. Other things you might want to know about:

• There are two new settings to adjust the amount of time full URLs are cached if retrieving a shortened URL fails and to adjust the amount of time before a request for a short URL times out
• If you were using the "Record Shorten" module, its list of shortened URLs has moved to the Reports section (admin/reports/shorten).
