Fastboot support and SEO mode

I haven't used ember-light-table in Fastboot yet. I would expect that it should run without problems, since users haven't voiced complaints yet. Did someone already try it?

I think a Fastboot enabled SEO mode is an interesting idea. The markup generated by ELT is a bit strange. The table is fragmented into two / three separate `` tags. I can imagine that this doesn't make much sense to search engines / crawlers.

If we're running in Fastboot, we could generate a more standards compliant markup.

Fastboot currently has no notion of "rehydration", but rather rerenders the whole component and replaces the server-side generated tags. For the most part, I don't expect this to cause any problems / layout flashes. However, fixed headers / footers could cause weird behavior, because of vertically overflowing table content (rows).
