[AndyB] Convert image media gallery 1.3

Converts media gallery tags to attach tags.

When the gallery embed button (camera icon) is used to insert images into a post, by default these tags are inserted as media tags. The problem with this approach is that when viewing a thread and clicking on an image which has been linked to media gallery, the image is opened in media gallery instead of a lightbox. This add-on converts media tags to attach tags so the user always remains in the thread and clicking an image always opens in a lightbox.

Question and Answers:

Q: Are media gallery attachments reused?
A: No. Each post attachment is saved separately which ensures that if the media gallery attachment is deleted the attachment in the post remains.
