Show/Hide Speedbar // Save Options

[David Reitter]

"Save Options" doesn't save the state of the speedbar, even though  
the speedbar is activated via the Options menu and Save Options  
otherwise saves all such preferences. That's confusing and I'd say  
it's a UI bug.

I couldn't easily implement it though, since the speedbar is not  
implemented as global minor mode that just needs to be toggled. I  
suspect there could be a customization variable which, when set, pops  
up the speedbar. This variable could be toggled by the menu and it  
could be saved by `menu-bar-options-save'.

The alternative, i.e. moving the speedbar out of the Options menu  
wouldn't be so great, since it provides great and useful  
functionality that should be readily available. (It's nicely  
designed, by the way, congratulations to whoever did it.)

Also, the chosen settings (in particular what is chosen in the  
"displays" menu, which would be `speedbar-initial-expansion-list- 
name', I think), should be customizable and easily savable as default.
