Issue Forms - File attachments #2
Description
Currently when attaching files it it necessary for each one to upload one at a time before the form is submitted. Needless to say this can lead to conditions where orphaned files can accumulate and is not ideal.
Instead, I'd like for the issue creation and editing forms to instead act more like conventional HTML5 upload boxes that let you add to a list of files to upload and then only upload them once the form itself is actually submitted. Preferable if whatever solution is devised does not require a dependency on jQuery or any other external javascript package.
