#11 two file issues under windows.

[Torrero]

I've fount two file issues. Both under windows.

1. Can't save file. Becuase of opened handle, rename fails. Solve - move close handle code before saving database;
2. attaching binary file or text file with CR,LF line-breaks not working - size mismatch. Solve - use '<:raw' in open. binmode will work too.
