sql.py: mk_insert_select(): embeddable: function_name is first line of query for clarity, and to reduce length from including the column names. This also fixes the problem of double quotes around column names in the previous function_name.

sql.py: esc_name_by_module(): Double embedded quotes to escape them instead of removing them

sql.py: put_table(): Use "-" to separate temp table suffixes from into table name

db_xml.py: into_table_name(): Format relational functions' into table names as a function call on the value column, using special chars for readability

sql.py: run_query(): Exception parsing: Use "(.+?)" wherever possible to match names containing special chars

sql.py: clean_name(): For clarity, just remove '"'s, so that "."s are preserved and show the path structure of the input name

db_xml.py: put_table(): sql.put_table(): Name the into table ...literal instead of ...value if the value column is a literal value

bin/map: Logging: log(): Remove extra debug info from DB query messages and format level 1.5 (summary) messages as Redmine list items

sql.py: put_table(): Renamed temp_prefix param to into and allow it to be a sql_gen.Table object. Use into directly as the pkeys table, and make its default value be `out_table.name+'_pkeys'`.

db_xml.py: put_table(): Pass custom temp_prefix to sql.put_table() for relational funcs, so that their value param's input column name is included in the temp table name
