Add Visual Studio 2012 support to the redesigned designer support installer.
Allow opened connections to skip adding the extension functions included in the interop assembly via the new NoExtensionFunctions connection flag.
Support loading of SQLite extensions via the new EnableExtensions and LoadExtension methods of the SQLiteConnection class. Pursuant to [17045010df].
Add notifications before and after any connection is opened and closed, as well as other related notifications, via the new static Changed event.

All applicable calls into the SQLite core library now return a SQLiteErrorCode instead of an integer error code.
Make sure the error code of the SQLiteException class gets serialized.
Make the test project for the .NET Compact Framework more flexible.
When available, the new sqlite3_errstr function from the core library is used to get the error message for a specific return code.

Implement more robust locking semantics for the CriticalHandle derived classes when compiled for the .NET Compact Framework.
Cache column indexes are they are looked up when using the SQLiteDataReader to improve performance.
Prevent the SQLiteConnection.Close method from throwing non-fatal exceptions during its disposal.
Rename the interop assembly functions sqlite3_cursor_rowid, sqlite3_context_collcompare, sqlite3_context_collseq, sqlite3_cursor_rowid, and sqlite3_table_cursor to include an "_interop" suffix. ** Potentially Incompatible Change **
