[slim-vim] the slime- prefix

[Larry Clapp]

A note on the "slime-" prefix naming convention (slime-connect,
slime-disconnect, slime-this, slime-that): slime.el uses that naming
convention because Elisp doesn't have packages.  Since we do, I would
rather just use the package name: slime:this and slime:that.  It bugs
me to have to say slime:slime-this and slime:slime-that, you know?

It *has* occurred to me that keeping the exact same function names
*may* make it easier to keep in sync with slime.el, so I acknowledge
that reasonable people might disagree and that making such a change
involves trade-offs.

What does the group think?
