Externally served attachments naming [ Feature requests ]

[mooomooo]

The externally served attachments functionality is great, thanks for that @fancypantalons! Two additional features that could make it even better:

• [x] I think sometimes libmagic fails to detect the proper file type (I've seen image/gif and video/mp4 attachments result in .???). Perhaps in such cases, it can split the attachment type and use the part after the / as the appropriate extension? (handled in #39)
• [ ] It would be nice to rename the files to something more useful -- perhaps allow a formatstring option that lets you select variables like sender name, recipient name, date/time string, etc. ?

For Pidgin users, the purple xfer API would be the most sensible choice. Upon receival, a dialog is opened "where do you want to save this file?" – this functionality already exists within libpurple. However, I do not know how bad this would be for bitlbee or spectrum users.
