bug 1009: id variables renamed, added document_id to the document.

cached->id => cached->cache_id
document->id => document->cache_id
onload_snippets_owner => onload_snippets_document_id
Added the distinct document->document_id.
Always reset ecmascript when a document changes for example a next chunk
of it is loaded.
