Text-slicer: Switch from weaving with tags to lists alone

Many reasons:
* to allow subtrees to be grafted more easily
* to keep the tags for an entry clean by removing structural tags and
leaving the semantic tags
* to avoid the duplication of expressing the same relationship through
both the tags and list fields

+This plugin contains tools to help work with documents that are structured as a hierarchical outline of tiddlers.  The structural relationships within the document are expressed as lists: for example, headings have a list specifying the content to be shown under the heading.
 
 TiddlyWiki is built on the philosophy that text is easier to re-use and work with if it is sliced up into separate chunks that can be independently manipulated, and then woven back together to make up stories and narratives for publication.

-Note that the relationship between the document and component tiddlers is that the components are listed in the ''list'' field. This differs from the relationship between headings and their components, which use the ''tags'' field of the components to tie them to the heading.
