removed functions set_eye_dir, add_builtin_shape, del_builtin_shape which were mistakenly added to version 1.41 (these are not really necessary and change module state, which is a Bad Thing)
documentation: added 'twang bra-strap' to acme shape description
tests: merged old 13_to.t, old 12_Beer.t to new 19_surrounds.t new Test::Pod test, 18_sky.t 11_bold.t now tested in taint mode (no banner test) 12_Beer.t now banner test only (not taint safe)
