Added the behavior of inserting multiple images through the insert
dialog, which is similar to DnD.
The method for creating a dialog box for inserting images has been
extended to allow the selection of multiple images: aDlg.setMultiSelect(true).
File selection is now handled as a list instead of a string.
Previously, when inserting an image into an area with another image,
the new image was inserted next to it, although it was expected to replace
the existing image, similar to other modules. In the current patch, when
inserting a single image through the paste dialog or DnD into an existing
image area, the existing image will be replaced. However, if insert
multiple images into an existing image area, the new images will be inserted
next to each other. This behavior is consistent with other modules.
