Remove attach dialog

This was used when you pressed the "Attach file/image" button but had an
image copied to your clipboard - allowing you to select from either
source. This is a weird thing to ask, the button should always prompt
you with a file dialog.

It's still possible to paste an image from your clipboard with CTRL+V,
but there isn't a way to do it via right-click yet.

Fixes #712
