file upload --- acts_as_attachment or file_column

1) patches welcome :slight_smile:
2) I just make the mods in the model. If I want a custom file naming
scheme, I typically override #full_filename.

It is easy to write your own, but after awhile you start running into
the same problems over and over again. Thats why I wrote
acts_as_attachment.

Well, I also wrote it to store files in the db (which file_column
doesn't do). It didn't take long before I added file system support,
which is what I primarily use now.
