Implement a basic SQLite dialect.

[lnchan]

This dialect allows for supporting the same REPLACE INTO syntax supported by MySQL, without changing the quote format or other behaviors. This allows the dialect to also be extended in the future with SQLite-specific syntax.

Alternatively, the REPLACE INTO syntax could be made to be used without any dialects.

Thanks! I'll take a look at this when I get back from vacation in a week or so.

Given that REPLACE INTO doesn't seem to conflict with any other dialect, I think your suggestion to just implement it in the "ANSI" core makes sense (since it also removes a weirdness caused by trying to mix MySQL and non-MySQL code, given that the MySQL dialect is side-effecting right now).
