Support alignment

[mforkel]

The plugin seems to have no support for aligning the pasted image.

A simplistic implementation could use the media manager's alignment settings similar to what dw_mediamanager_item_select does in lib/scripts/media.js, e.g.:

+                            alignleft = dw_mediamanager.align === '2' ? '' : ' ';
+                            alignright = dw_mediamanager.align === '4' ? '' : ' ';
+                        }
                         $box.find('.content').addClass('success').text(data.message);
-                        insertAtCarret('wiki__text', '{{:' + data.id + '}}');
+                        insertAtCarret('wiki__text', '{{' + alignleft + ':' + data.id + alignright + '|}}');
                         $box.delay(500).fadeOut(500, function () {
                             $box.dialog('destroy').remove()
                         });

But I think it would be cleaner to make alignment a function of dw_mediamanager with its default settings accessible in the DokuWiki configuration and additional settings for the imgpaste plugin.

I agree some setting for the default syntax (nolink, detail, alignment, ...) should be added to implement this correctly.

The plugin now supports other media (non-images) as well. Ideally PDFs shouldn't get any alignment.
