main_window: read image dimensions for bookmark popout aspect lock

Browse Source 
Bookmark Post objects have no width/height (the DB doesn't store
them). When opening a bookmark in the popout, read the actual
dimensions from the cached file via QImageReader so the popout
can set keep_aspect_ratio correctly. Previously images from the
bookmarks tab always got 0x0, skipping the aspect lock.
