Mark softer-dark-theme as safe on 24.3.91

It may be that 24.4 rc1 is using a different checksum or hash than my
Windows system.
Don't load rfringe on emacs without fringe support
Bind the Mac command key to Meta another way
Load ws-butler without hanging daemon mode
Delay load desktop to avoid hanging daemon mode

Load it when Emacs is started without the --daemon switch, or when an
emacsclient opens a new frame or switches buffers.  In these cases we do
not have to worry about questions being asked without an interface to
answer them.  One oddity is that if emacsclient visits a file that is in
the desktop, a spurious question may be presented.
