Allow editors to set META tags on each page

[mstralka]

It would be great if Apostrophe let an editor set the META tags on each page. I know they're not very popular anymore and most search engines ignore them, but clients think it's really important.

This request came from this discussion:

We're going to do something like this, and implement the meta tags in our own built-in search engine, which will actually make them useful (for an internal search there's no spam problem).

But be sure to send your clients to this page:

And make sure they note that it's official Google truth. (:

This ticket has been resolved as of wjohnald subversion commit: 1988.

Tags have been "boosted" in the Lucene search index allowing page editors to give more weight to keywords in site-wide search.

Descriptions have been "boosted" a bit less than tags by the same reasoning.

Tags appear in the source as meta keywords.
Descriptions appear in the source as meta descriptions.

This works well. I tacked on a couple of if statements to avoid overring view.yml's settings if the page has no tags or description.

This is currently in the /features/wjohnald branch. It should be merged to the trunk sometime Friday.

Does this need to be assigned to Rick, Jake or John to be styled?

Is this working in the new page settings design?

[tboutell]

Yes, it is in the new page settings dialog in the trunk.

There is a ticket for Dan and John to look at the tagging widget (with me perhaps) and fix it to work properly in a "normal" form. I think that could be something we beat into submission on Friday. In the meantime the tag field is a straight-up comma-separated text field, which actually works pretty okay but of course we want the nicer features of John and Dan's thing. See #534

Otherwise it looks pretty reasonable but Rick and John should probably put a toggle in to collapse the "meta" stuff the way you can collapse the other optional stuff. I'll open a styling ticket for that issue.

See also #535 for a known Apostrophe bug that is not the fault of this new code but needs to be addressed before it's easy to work with.
