Log Message:
-----------
Working support for sessions stored in the database.
/contentSystem.class.php:
* initialize_locals():
-- start database-based session storage if SESSION_DBSAVE is a
properly set constant.
/cs_session.class.php:
* __construct():
-- ARG CHANGE: DEFAULT VALUE CHANGED: #1 (from 1 to true)
-- when passing a boolean true as arg #1, a session was created which
was literally named "1" (the bool was interpretted to a string val).
/cs_sessionDB.class.php:
* REMOVE LOGGER STUFF:::
-- sessdb_table_exists()
-- load_table()
-- is_valid_sid()
-- sessdb_open()
-- sessdb_close()
-- sessdb_read()
-- sessdb_destroy()
-- sessdb_gc()
* __construct():
-- remove logger stuff
-- move session_set_save_handler() call to just before the call to
the parent's __construct().
* sessdb_write():
-- removed logger stuff
-- set array signifying how to clean the fields.
-- pass the cleanString var to string_from_array()
