Jermolene 32f6d7f1b0 Revert getTiddlerData() and add getTiddlerDataCached()
For backwards compatibility, we now explicitly request the cacheable
version of this method.

Fixes #1873

type: application/javascript
module-type: command
Command to save the subtiddlers of a bundle tiddler as a series of JSON files
--savelibrarytiddlers <tiddler> <pathname> <skinnylisting>
The tiddler identifies the bundle tiddler that contains the subtiddlers.
The pathname specifies the pathname to the folder in which the JSON files should be saved. The filename is the URL encoded title of the subtiddler.
The skinnylisting specifies the title of the tiddler to which a JSON catalogue of the subtiddlers will be saved. The JSON file contains the same data as the bundle tiddler but with the `text` field removed.
