FR: SQlite support

[Vuizur]

Hello,

thanks for releasing this super useful project!

I only wanted to say that it would be pretty cool if one could connect to a local sqlite database file.

I tried creating a basic class for sqlite in my branch here, it currently seems to crash because it doesn't have any files under checks/sqlite and I am not quite sure how to resolve that.

Hey @Vuizur , sorry about the late reply.

For a start, just copy a simple check over from a mysql or postgres directory :)
