Fix attachment issues

Browse source 
Fixes https://github.com/PrivateBin/PrivateBin/issues/315
The attachment viewer is also used for storing to be uploaded
attachments, which caused some confusion in handling them.
I also tried to add some comments clarifying it as it seems to work.

Additionally I fixed the issue that you could submit an empty paste and
it was not rejected.
