Changes since last update: Remove use of Learner's server version of item_info.txt, will be included directly in the client. Move check for astrology messages before #ignore filter as can prevent the astrology window from opening. Release candidate time, enable NEW_EYES by default.

Minor update

Features: Add #relogin command: tests server connection and moves to disconnected state if the test fails. Use the same selected/highlighted colours for storage category as elsewhere in the UI. The You'd need to use binoculars server message when you've opened a book and switch maps won't show any more if the book is closed.

New character: Fixed missing character animations when race or gender changed. Fix parse_2d0() for NEW_TEXTURES - ground items like skeletons are visible again.
