	* Version 4.0.0: Major version increase to warn of potential
	backwards incompatibility.
	* NEWS: Document potentional backward incompatible changes
	* db-mysql/mysql-sql.lisp: Changes session SQL mode to ANSI immediately
	after connecting. This may break compatibility with some applications
	who are using non-ANSI features with MySQL. This change is required to
	properly support view-classes using a string as their :base-table
	attribute. This allows users to specify the case of table names.
	This is feature is even	more essential for MySQL itself since MySQL
	uses case-sensitive table names. Use connection-based database-create
	and database-destroy rather than trying to invoke command-line mysql
	utility. Remove automatic upcasing of strings from list-indices.
	* db-postgresql/postgresql-sql.lisp: Use connection-based
	database-create	and database-destroy rather than trying to invoke
	command-line utilities.
	* db-postgresql-socket/postgresql-socket-sql.lisp: Use
	database-execute-command rather than execute-command for
	database-{create,destroy}. Connect to postgres database
	rather than template1 for those database creation/deletion.
	* sql/metaclasses.lisp: Store the string value of :base-table if a
	string is provided. Perform sql-escape at time of view-table name
	creation.
	* tests/test-init.lisp: Use "ej_join" as a string, rather than a
	symbol, since "ej_join"	is specified as :base-table. Clear the
	expression output-cache in case the code for generating sql output
	has changed.
	* test/test-oodml.lisp: whitespace fix
	* sql/ooddl.lisp: Use quoted string for primary key constraint if
	table name is specified as a string.
	* sql/oodml.lisp: Don't convert a string view-table name to database's
	default case.
	* sql/expressions.lisp: Properly handle table and attribute identifiers
	when they are a string. Do not change case of symbols to match database
	default case.
	* sql/operations.lisp: Change multiword symbols to upper case.
	* sql/fddl.lisp: Quote base-table if a string to preserve case
	for drop-table and create-table.
	* tests/test-syntax.lisp: Add tests of low-level string attribute
	identifiers.
