Astro-satpass

Changes for version 0.026_02

The Astro::Coord::ECI azel() method now returns velocities if these are available. The transverse velocities (azimuthal and elevational) are NOT corrected for the Coriolis effect. Added Astro::Nova to the Astro::Coord::ECI 'SEE ALSO' section. Date::Manip is no longer required. If it is not available, the 'satpass' script will use a home-grown pseudo-ISO-8601 parser instead. The t/parse_time.t test was added to make sure this works as advertized. Have 'authortest' run the normal tests without any of the optional modules. This requires either Test::Without::Module or Devel::Hide. If neither is available, 'authortest' will not attempt these tests. Remove the last vestiges of the $ENV{DEVELOPER_TEST} machinery. Rewrote xt/manifest.t to use Test::More.

All modules' versions set to 0.026_01. In the future all modules in a given release will have the same version number. Convert all modules to the CPAN-recommended license. Author tests no longer rely on environment variable DEVELOPER_TEST. Instead, they are executed by ./Build authortest. This means author tests are no longer available via the ExtUtils::MakeMaker build. Astro::Coord::ECI Modify correct_for_refraction() to work down to (and a bit below) the horizon setting if that is negative. Thanks to Vidar Tyldum Hansen of Kongsberg Satellite Services AS for identifying the need for this, and working with me on it. satpass Add the 'refraction' parameter, to allow the user to turn off atmospheric refraction (it is on by default).
