00c5a49a87 Option to ignore inserts if primary key exists already 
Support for SQLite's INSERT OR IGNORE

In the API layer it looks like this:

    fresh_db["test"].insert({"id": 1, "bar": 3}, ignore=True)

For the CLI layer it looks like this:

    $ sqlite-utils insert data.db dogs dogs.json --ignore

e1ca938aa1 table.add_foreign_key(column, other_table, other_column) 
New mechanism for adding foreign key constraints to an existing SQLite
table.

SQLite ALTER TABLE does not support this out-of-the-box, so I instead
had to write some careful code that uses PRAGMA writable_schema = 1 to
directly modify the sqlite_master table.

0aa28293ad Fix compatibility with SQLite prior to 3.16.0 
pragma_index_info() and pragma_index_list() were introduced in 3.16.0 but the
version of SQLite running in Travis CI is earlier than that, hence the test
failures:
