toc-sequence and item-sequence should be allowed inside regular sequences

[GoogleCodeExporter]

toc-sequence and item-sequence should be a group of blocks inside regular 
sequences instead of being sequences of their own. Doing so would eliminate the 
need for on-toc-start, on-toc-end etc. It would also enable combining several 
collections under the same heading. And eventually, it could enable TOC in the 
main flow or placing all footnotes at the end of the document.

E.g.

<dynamic-sequence sheets-max="10">
  <insert-toc toc="full-toc" range="volume">
    <on-volume-start 
    ...
  </>
  <insert-refs-list collection="endnotes" range="volume"  fallback="collection-id">
  </insert-refs-list>
  <list-of-references collection="endnotes" range="volume" ...>
    <on-page-start
    ...
  </list-of-references>
</dynamic-sequence>

As it turns out, on-collection-start and on-collection-end are quite handy, 
because the dynamic sequence may contain static blocks, but they are rendered 
regardless of whether a list-of-references is rendered or not.

This has been implemented for collections (but not yet for toc)

• Changed title: toc-sequence and item-sequence should be allowed inside regular sequences

[bertfrees]

@joeha480 Does this also include allowing toc-sequence and list-of-references inside a regular sequence (not dynamic-sequence)? The problem I'm currently having with dynamic-sequence is that I don't want this behavior (quoted from OBFL spec):

[...] its existence depends on the existence of generated content. Without any generated content, the sequence should be excluded entierly.

That's the idea, yes.
