[patch] burncd: honour for envar SPEED

[Alexander Best]

here's the final patch. would be great if somebody could commit this one. the
only thing i'm not 100% sure about are the burncd(8) changes. i'm not that
familiar with the man syntax.

thanks go out to keramida@ and des@ for their help.

...just realised the topic makes no sense. ;) what i meant to write was
probably "[patch] burncd: honour envar SPEED". ;)
