* Release 1.4.

* (all): Updated the copyright years for 2008 on some of the files
in the current release and added a copyright statement to any files
previously lacking one.

* LICENSE: Replaced the previous BSD-like license with the one used
by the OpenBSD project (modeled after the Internet Software
Consortium's, a two-clause BSD license removing language made
unnecessary by the Berne convention); this new license is
functionally identical to the old one, just more terse and openly
recognized.

* weather: Clarified function parameters in calls from the wrapper
script to ease future ABI changes in the underlying module.

* weather, weather.py: Some extra comments were added to the source,
indentation style was updated from tab characters to three-space,
and lines longer than 79 columns were refactored or otherwise split.

* weather.1, weather.5, weather.py: Added an flines option to allow
the maximum number of forecast output lines to be shortened. Added
furl and murl options to allow overriding of the default current
conditions and forecast data retrieval URLs. Added a headers option
to allow overriding the default list of header names for current
conditions data filtering. Added a quiet option to suppress the
preamble lines and indentation for both current conditions and
forecast output.

* weather.py: Replaced the hardcoded fallback default METAR station
ID and forecast city/state abbreviation with error messages to
minimize confusion when necessary values are omitted. Adjusted a
couple of hard-coded error message strings to be consistent with the
output format of the option_parser module. Switched from urllib to
urllib2 for retrieving data, providing a simpler means to detect and
report retrieval errors. Upped the version to 1.4.
