First version for save - not working now.
Manual.rst: document config var SYSTEM_DIRTY_RECORD_TIMEOUT_SECONDS.
QuickFormQuery.php, Dirty.php: extend to support QFQ/save().
Client.php: fixed broken PHP Unit test
Config.php: set default for dirtyRecordTimeout.
BuildFormBootstrap.php: No dirtyUrl if dirtyMode=none.
formEditor.sql: extend definition to Form.dirtyMode, new table 'Dirty'
Fixed several unit tests for new tables.

Fix #3419 / typeAheadSql: Array mit nur einer Spalte oder andere KeyNamen als key / value werden nicht korrekt behandelt.
TypeAhead.php: Added detection of missing ... LIMIT in FE_TYPEAHEAD_SQL. Make resultset always a two column array with columns key/value.
Database.php: Added function hasLimit() and makeArrayDict().

FormAction.php: cleanup
Store.php: cleanup
Database.php: Added TRUNCATE
fixtures/Generic.sql: added Person.adrId - just as testcase

Database.php: Fixed bug that INSERT returns affected rows. Correct is last_insert_id. Moved 'REPLACE' to behave like 'INSERT' instead of 'UPDATE. Extended Tests

Report.php, Database.php: triggerReport() supports stat[] with num_rows, affected_rows and insert_id. rowTotal does not contain anymore inserId (last_insert_id) from fired INSERT queries. Instead num_rows or affected_rows are choosen. New: <level>.line.inserId contains the insertId.

Database.php: sql(..., ROW_IMPLODE_ALL,...) have been confused by columns with identical columnnames (MYSQLI_ASSOC). Has been fixed now by using MYSQLI_NUM.

Database: Moved implementation from PDO to mysqli. Reason: mysqli_num needed for `report`, but PDO can't fetch column names than.

Database: renamed rowCount() to getRowCount(). Additonal error message for sql(), New: dbLog(). prepareExecute will log all fired queries.
