Use a hyphen to separate namespace from function

From http://www.emacswiki.org/emacs/Namespaces:

> You should choose a short word to distinguish your program from other
> Lisp programs. The names of all global variables, constants, and
> functions in your program should begin with that chosen
> prefix. Separate the prefix from the rest of the name with a hyphen,
> `-`.
>
> This practice helps avoid name conflicts, since all global variables
> in Emacs Lisp share the same name space, and all functions share
> another name space.
>
> Use two hyphens to separate prefix and name if the symbol is not meant
> to be used by other packages.

I'm going to have to keep working on this based on the different screen
sizes I use.
Defer loading of SLIME
Set initial major mode to Org mode
Set contents of initial scratch buffer
Tidy up SLIME setup
Remove all SLIME setup

It takes half a second to load, and I'm not sure I'm even using
it. Until I notice a missing feature I'm leaving this out.
