Subject: [PATCH 09/17] add tag table to ZeroBlog,to support blog tags, index
 by tag

blog can have a space splited tag list,these value-post_id map stored
in tag table. I think best way to implement this should be insert
trigger and CTE(requires sqlite 3.8.3), but zeronet didn't assume this,
so this implements by maintain tag table in frontend (coffeescript)

Subject: [PATCH 12/17] implements auto TOC by tag function

support three type TOC: index.html has link to "?Toc=tagAll",
which generated a overview tag index page as:

tag1: n post(s) ---> links to ?Toc=tag:tag1,shows all posts has tag1
tag2: m post(s)
...
untagged: x post(s) ---> links to Toc=tagNone, shows all posts without tags.

same post may belongs to many tag,leads too many duplicate, so tagAll
didn't show every posts. user can jump to extactly tag list from the
"tag list" part of every post (in previous commit)
