cwdb2/Import

We’ve finally got the cwdb2/Import functionality working and semi-tested.

Currently the ability to pre-select what’s being imported, be it just the first post, or the whole thread, has been removed. In addition, the ability to import an entire thread with the parent-child relationships intact is gone. I’ll fix this later.

The usual applies: Import things and try to break it. Post a comment here if you find anything.
