[orca] Move some technical-content symbols to mathsymbols.py and remove duplicates

[Joanmarie Diggs <joanied src gnome org>]

commit 517bcccbe9d5f3a4d05f5ba7b985589954594821
Author: Joanmarie Diggs <jdiggs igalia com>
Date:   Mon Mar 23 14:38:57 2015 -0400

    Move some technical-content symbols to mathsymbols.py and remove duplicates
    
    Because there are far more symbols than we can ask translators to translate,
    we have fallback code so that we at least speak something for the symbols
    which we think are unlikely to be encountered, and likely to not be presented
    by espeak. This range-based code was stomping on a few symbols which were
    actually localized. Moving them to mathsymbols.py will stop the stomping.
    Also removed some duplicates.
