Show DB backend on home and model creation pages

Looks fine to me. Things are starting to get a little cluttered on the home page, but @jmancewicz should be revamping the whole thing with #240 soon anyway.

note: doesn't show a badge for generic datasets

Let's just put an LMDB badge on all of them since that's the only backend supported at the moment anyway. It would probably be a good idea to actually add a backend field to generic datasets too, since we'll be supporting more options in the future.

Actually, in my understanding image dataset jobs (neither generic nor classification ones) don't have a backend field. For image classification datasets, the information is coming from the training DB task (there is an assumption that an image classification dataset uses a consistent DB backend). The thing is generic datasets don't have a training DB task. Where do you suggest I add the backend field?

Good point, that is a little strange.

In the AnalyzeDbTask's.
