Group the oracle-related renaming into functions in oracle.py ; check whether a renaming was already done before doing it, likewise check if a renaming was done before undoing it
Remove table renaming from connect(), instead require 'from pokedex.db.oracle import *' followed by 'rewrite_long_table_names()';
Grouped all the hackery manipulations of the names in oracle.py, easily reversible too. Fixed dump to read from short named columns but dump in long named files. Load/dump now uses oracle.py to handle the name stuff.
