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

title: $:/core/modules/upgraders/themetweaks.js
type: application/javascript
module-type: upgrader
Upgrader module that handles the change in theme tweak storage introduced in 5.0.14-beta.
Previously, theme tweaks were stored in two data tiddlers:
* $:/themes/tiddlywiki/vanilla/metrics
* $:/themes/tiddlywiki/vanilla/settings
Now, each tweak is stored in its own separate tiddler.
This upgrader copies any values from the old format to the new. The old data tiddlers are not deleted in case they have been used to store additional indexes.
