schemas/*.sql: Updated for PostgreSQL 9.1.6, which has standard_conforming_strings = on (which affects \-escapes in string literals), escape_string_warning not explicitly set, and uses ALTER TABLE ONLY instead of ALTER TABLE

README.TXT: Removed step to manually run make_analytical_db, now that this is done automatically by import_all. Added separate instructions to remake the analytical DB.

import_all: Change to main directory make targets are run from. Use relative paths to bin/ commands, which is possible now that the current dir is set.

import_all: Create a background process that waits until the import is done and then runs make_analytical_db

Added waitpid

import_all: Documented that `wait %1` waits for asynchronous commands

root Makefile: VegBIEN DB: DB and bien user: mk_db: Also install hstore extension. Note that this is only supported by PostgreSQL 9.1+.

input.Makefile: Editing import: Updated queries for current schema

inputs/.geoscrub/geoscrub_cultivated/create.sql: Fixed bug where need to filter out NULL lat/longs because primary keys can't contain NULL values

schemas/py_functions.sql: Changed function languages to plpython3u to match the new installed version. Note that plpythonu is not available on Mac under PostgreSQL 9.1.6.
