Classify: Avoid unneeded new / delete operations
...
Both class variables BaselineCutoffs and CharNormCutoffs were pointers
to fixed size arrays which were allocated in the constructor and
deallocated in the destructor. These two extra allocations and two
extra deallocations can be avoided.

Font and classifier output structure cleanup.
...
Font recognition was poor, due to forcing a 1st and 2nd choice at
a character level, when the total score for the correct font is often
correct at the word level, so allowed the propagation of a full set
of fonts and scores to the word recognizer, which can now decide word
level fonts using the scores instead of simple votes.
Change precipitated a cleanup of output data structures for classifier
results, eliminating ScoredClass and INT_RESULT_STRUCT, with a few
extra elements going in UnicharRating, and using that wherever possible.
That added the extra complexity of 1-rating due to a flip between 0 is
good and 0 is bad for the internal classifier scores before they are
converted to rating and certainty.
