Release of version 1.2.

This is a maintenance release which fixes a nasty bug which was preventing the processing of single-part articles which contained a part/whole desginator "(1/1)". This is a one-line change, but you are strongly urged to upgrade.

Upgrading from any previous version to v1.2 is easy - just replace the executable. Your existing .ubhrc and .newsrc files are entirely forward compatible with v1.2.
