Release of version 1.3.

This is a maintenance release which fixes several particularly nagging problems:

• Will detect a dropped NNTP connection during group() and body() calls, and will automatically reconnect, re-authenticate (if necessary), re-issue the group() call, and proceed from where it left off. Thanks to Adam Rice!
• Eliminated the ugly goto's in the reconnect code.
• Made uudecode search for "begin" case insensitive. Thanks to Michael Tiedge!
• Now ignores trailing whitespace in ubhrc values. Thanks to Hsiao-Yu Chen!

Upgrading from any previous version to v1.3 is easy - just replace the executable. Your existing .ubhrc and .newsrc files are entirely forward compatible with v1.3.
