Allow pasting attachments/images from clipboard

[idelsink]

What is the problem you are trying to solve with this feature?

I quite often quickly copy an image from somewhere and want to paste it into an existing item or when creating a new item. But because I cannot paste it directly when creating/modifying an item, I need to either save the original picture or open something like gimp to save it to a file to then upload it into homebox.

What is the solution you are proposing?

I would like for homebox to allow pasting from the clipboard for attachments or pictures to make it very easy to quickly add items

What alternatives have you considered?

Additional context

I'm running Version: v0.18.0 ~ Build: 3a32804
