<!-- {#
This template is shared by the new thread, reply and post-editing pages.
The main display differences between the different editing styles are the
headline of the page ("Submit new thread", "Reply to thread", "Edit post")
and whether or not the subject line field is displayed in the input form.
Every one of these pages can have a variable length list of alerts submitted
into the template, which will be rendered as Boostrap alert boxes above the
user input form.
