vegbien.sql: Removed the taxonOccurrence:aggregateOccurrence 1:1 constraint

sql.py: truncate(): Use run_raw_query() instead of run_query() because truncate() does not use the recover functionality of run_query(). Also, in the profiling output, this separates the "normal" SQL statements (which use run_query()) from the "core" SQL statements (which use run_raw_query()).

vegbien.sql: Added indexes for each field in party used in duplicate elimination (for use by sql.put()'s DuplicateKeyException handler)

sql.py: run_raw_query(): In debug mode, print query after params have been substituted in

sql.py: Fixed index_cols() to handle UNIQUE indexes with expressions, whose column names are stored in a different format

sql.py: Print warning if SELECT statement missing a WHERE, LIMIT, or OFFSET clause. Changed bin/map DB input get-all-rows statement to pass start=0 to suppress this warning for that statement.

db_xml.py: Added start option to get() that passes through to sql.select()

sql.py: Added start option to select() to set the OFFSET

sql.py: If run_raw_query.debug flag is set, print each query executed (on a single line)

strings.py: Added one_line() function to make a string all on one line
