Grammar: Support ON INSERT in foreign key clauses

Allow ON INSERT in foreign key clauses like this:
CREATE TABLE x
(
	y INTEGER REFERENCES ref(id) ON INSERT CASCADE
)
Note that ON INSERT is allowed by SQLite but missing in the SQLite
documentation.

This partially fixes EoD's problem in issue #63.
