New speedbar version

[Nick Roberts]

 > A new version of speedbar.el has been checked in.

The file gdb-ui.el has used speedbar.el over the last two years to display
watch expressions.  Now, with supposedly a month or so to go before the
release, it doesn't.  There are 290 differences between this version and the
previous one.  The ChangeLog entry is:

        * speedbar.el: New version 1.0pre3.

If this is deemed reasonable behaviour then its probably not worth debating
the issue.
