join: Match terms case-insensitively

Added inputs/TEAM/

sql_io.py: put_table(): Creating the into table: into_out_pkey: If is_function, just use "result" as the output column name, without prefixing the function name. This shortens the table names of function calls on function calls, which need a fixed column name to detect which columns are function results and use just the table names for those columns.

input.Makefile: Documentation: $(steps): Fixed bug where import make target needed to be changed to new single-table import target

schemas/vegbien.sql: analytical_db_view: Changed LEFT JOINs to JOINs where tables contain information that's required for the analytical DB. This should also enable the PostgreSQL query planner to make additional join optimizations, in the hopes of avoiding disk-space-intensive hash joins.

Replaced repr() with strings.urepr() (or equivalent) everywhere needed, to avoid future UnicodeEncodeErrors

Replaced str() with strings.ustr() (or equivalent) everywhere needed, to avoid future UnicodeEncodeErrors

sql.py: map_expr(): Replacing without quotes: Don't match unquoted name where it's preceded or followed by '.', because this could be a '.' embedded in a punctuation-containing column name, such as those frequently used by column-based import. Note that because database-internal names currently do not contain punctuation, this situation only occurs when a database-internal expression (such as a check constraint condition) is replaced in two steps, and the first step introduces punctuation-containing column names into the expression.

schemas/vegbien.sql: project: Don't require projectname to be specified when sourceaccessioncode is provided

sql_gen.py: ensure_not_null(): If type_ is set, cast the column to it if needed
