schemas/*functions.sql: Renamed to *util.sql because now that these schemas are used by the new-style import scripts, there can be more than just functions in them

schemas/functions.sql: Added existing_cols()

schemas/functions.sql: col_type(): Fixed bug where a NULL col name crashed the undefined_column throw, because MESSAGE can't be NULL and the NULL name was nulling out the entire message

schemas/functions.sql: Added col_exists()

inputs/FIA/COND/map.csv: Mapped SLOPE, ASPECT

web/main/.htaccess: remove linewraps (of the form table.path.vg/_-term) used to create a newline for Google spreadsheets

inputs/FIA/*/map.csv: Replaced . between table and column name with newline, so that table viewers like pgAdmin will display both the table and column name at the left edge of the header cell, rather than displaying only the table name because the column name doesn't fit. This fixes the problem of seeing a bunch of columns whose names all start with a table name, and not knowing what each of them is. It also preserves the ability to see at a glance which table a column is in, which helps in navigating wide tables. Removed * before unmapped terms, because whether a term is mapped is generally obvious from the table name itself.

inputs/input.Makefile: %/.map.csv.last_cleanup: Run fix_line_endings after canon/translate to standardize Python's \r\n line endings back to \n. This prevents issues with mixed line endings because LibreOffice (and probably Excel) treat all cell-internal line endings as \n but row line endings as whatever the file had, while text editors like jEdit translate all line endings to whatever the autodetected line ending is. (This creates spurious line ending diffs when a map spreadsheet containing multiline cells is edited in a text editor.)

Added bin/fix_line_endings to standardize \r\n line endings to \n

inputs/FIA/COND/import: Renamed COND.oldgrowth to VegCore name oldGrowth
