TiddlyWiki.prototype.saveTiddler

The saveTiddler method of a TiddlyWiki class object is typically called in response to the author clicking the 'done' link after editing a tiddler.
This method takes six parameters:

• the old title of the tiddler
• the new title of the tiddler
• the tiddler's source code
• the name of the author
• the modification date
• the tags (as an array of strings).

This feeds directly into Tiddler's set method, and does not save changes to the document on disk.
