upgrading 1.0.3 to trunk 1682, forums - existing installation upgrade.

[DJPaul]

After upgrading an existing BP to the trunk, with regards to the forums, when upgrading with an existing bbpress install / config file. After you enter the path to your existing bbpress config file, and clicking the button, you get no feedback that something actually happened.

Also, I can forsee people trying to enter a path with '/bb-config.php' at the end. I think it'd be good if BP checked and cut that bit off the end of the string.

Also need to check for trailing slashes.

It'd be a good place here to mention that you can then safely remove your old BbPress installation and config file (but not the database).
