Allow to copy-paste an image as part of a form field for filling the task description, like its possible if one creates a task directly and fills in the description.

When pasting the image in the description field, its automatically attached to the task itself, as an attachment.

Forms only allow to attach a previously saved image as a file, this slows down the process of inputting data via form field significantly and prevents some users to report e.g. bugs with a helpful image.
