A gallery tag is parsed line by line, so captions
(and other image data) should not contain line breaks

Change I94f4fadd84cd3e prevents the gallery dialog from inserting
duplicate images into the gallery dialog after one request (e.g.
so double-clicking on an image in the search widget doesn't cause
the image to be inserted twice). However, galleries can
intentionally contain duplicates of the same image, so it is
possible to make a spearate request to insert a duplicate image.
When the dialog is first opened, it requests all the images in
the gallery at once, so the above change was causing the
duplicates in an existing gallery to be dropped. Duplicates
should be allowed to be inserted following this initial request.

Make new graphical interface for editing existing
galleries and adding new galleries.
NB The dialog does not yet support rich text in the
image captions, nor does it provide separate fields for
e.g. link, alt text, etc. These are dependent on parsing
the text within the tag, which is yet to be implemented
by Parsoid. For now, these attributes should be
specified in wikitext in the image-specific caption
field.
