Add a SQLiteConnection.open(int flags) method

[Former user]

Originally reported on Google Code with ID 2 ``` The SQLiteConnection class has a private open0 method that takes a flags parameter. These flags are passed to sqlite3_open_v2. But there is no public method to open a database providing some flags, like the thread-mode ones.

Can you add this method please?

```
