bin/map: Fixed bug where row count was off by one if all rows in the input were exhausted, because the row that raises StopIteration was counting as a row

main Makefile: VegBIEN DB: mk_db: Use template1 because it has PROCEDURAL LANGUAGE plpgsql already installed and we aren't using an encoding other than UTF8

Moved "CREATE PROCEDURAL LANGUAGE plpgsql" to main Makefile so that it would only run when the DB is created, not when the public schema is reinstalled. This is only relevant on PostgreSQL < 9.x, where the plpgsql language is not part of template0.

Renamed parallel.py to parallelproc.py to avoid conflict with new system parallel module on vegbiendev

Makefile: VegBIEN DB: public schema: Added schemas/rotate

bin/map: Fixed bug in input rows processed count where the count would be off by 1, because the for loop would leave i at the index of the last row instead of one-past-the-last

bin/map: Use the same XML tree for each row in DB outputs, to eliminate time spent creating the tree from the XPaths for each row

bin/map: map_table(): Resolve each prefix into a separate mapping, which is collision-eliminated, instead of resolving values from multiple prefixes when each individual row is mapped

bin/map: Moved collision-prevention code to map_rows() so it would only run if there were mappings, and so that it would run after any mappings preprocessing by map_table() that creates more collisions

bin/map: Prevent collisions if multiple inputs mapping to same output
