[CM] Snd 11.7

[Bill Schottstaedt]

Snd 11.7.

Michael Klingbeil found and fixed several bugs in locsig, and
        made several changes for ClozureCL in OSX.

s7: hash-table for-each and map are now entry-oriented.
    reverse of a hash-table swaps keys and values.

removed title-with-date (examp.scm), snd-gxutils.c,
    window-property, window-property-changed-hook, send-mozilla

checked: gtk 2.90.2|3|4, Fedora Core 13, mpfr-3.0.0, sbcl 1.0.40,
    autoconf 2.66, clisp 2.49
