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.

SEAM and SPLIT have been begging for a refactor for a *LONG* time.
This change does most of the work of turning them into proper classes:
Moved relevant code into SEAM/SPLIT/TBLOB/EDGEPT etc from global helper functions.
Made the splits full data members of SEAM in an array instead of 3 separate pointers.
This greatly reduces the amount of new/delete happening in the chopper, which is the main goal.
Deleted redundant files: olutil.*, makechop.*
Brought other code into SEAM in order to keep its data members private with only priority having accessors.
