pg_dump_vegbien: Enclose the schema name in "" because pg_dump requires this for schema names with special characters

inputs/import.stats.xls: Updated with stats from 2012-7-3 and 2012-7-5 imports. Note that the 2012-7-5 import was partial, so its stats can't be directly compared.

root Makefile: VegBIEN DB: Schemas: Added schemas/%/rm_indexes

Added mk_rm_indexes

sql.py: Added drop() and use it in drop_table()

debug2redmine: Remove profiling information from the logging output

sql.py: DbConn.run_query(): Only print notices in debug mode, because they are output with a log level higher than the debug verbosity threshold, and this avoid unnecessary overhead

sql.py: DbConn: Added profile_row_ct setting, which is passed to profiler.stop() in run_query()

bin/map: Logging: Raised debug-mode verbosity threshold to 1.5 so that in row-based imports, which have a default verbosity of 1.1, sql.DbConn.run_query() will not profile the query, to avoid unnecessary overhead

sql.py: DbConn.run_query(): Only profile queries in debug mode, to avoid unnecessary overhead when the run time will not be displayed
