Changeset 75c3ff7 for protocols/purple/ft.c

Timestamp:

Message:

Fixed sending with proper filenames by creating a temporary directory with
the file in it; protocol modules are mostly hardcoded to use the filename
from the filesystem with no way to override this.

Also improved robustness a little bit.
