 this patch seperates the logo detection from !ClassicCommDetector, and
 puts it in its own class. I've done the same for the scene change
 detection, I'll open a seperate ticket with a seperate patch later on for
 that.

 The new class, !ClassicLogoDetector, is currently still pretty intertwined
 with the !ClassicCommDetector. !ClassicCommDetector is putting pretty
 strong limitations on the implementation of a logodetector class, as in
 the current setup it gets one shot to search for a logo, and later on has
 to tell us if that logo is currently present in a  frame..   A
 logodetector has no freedom such that it might realize at the end of a
 recording that another logo is present, and that it would like to do
 another pass at the entire recording to look for this new logo again..
 anyway, stuff like that are likely future improvements.. first things
 first.

 This patch mantains functional equivalence to svn head. I've compared
 behaviour of snv head, and this patch on two recordings, and they had not
 only identical results, but identical verbose debug output.
