Rename SLDB symbols

[lassik]

Ref #41

DIME was forked from SLIME, and DIME currently defines symbols using SLIME's sldb- prefix. We should change the prefix.

In fact, SLIME itself is not following current Emacs Lisp namespace conventions since it uses sldb instead of slime as the prefix. Since we can start afresh with DIME we should follow the convetions.

I suggest changing sldb to dime-debug. The following would be the list of the new symbol names. Does it look reasonable?

Looks good to me.
