enhancements for the web ui front page

[yarikoptic]

I am a newbee to apine, thought to run a simple query, here is a webshot:

• first I tried to click on blue (link?) "click" but nothing happened... is it supposed to be a link? if not - choose different color/emphasis (e.g. not color but just bold?)
• I entered my query - "mri" but I guess it is not in the right syntax but I didn't spot a hint/pointer describing how query should look like. Would be nice to get some guidance for that ("Query is a set of field=value specifications" or alike), or may be a sample "interesting" query which would make user excited
• Whenever I got the result for dataset=ds001, was not sure what next I could do with them - nothing is hyperlinked anywhere (e.g. for the result ./examples/ds001.json)

Hey @yarikoptic! First: thank you for trying things out! I haven't really given this project much time, and certainly haven't tried very hard to make it useable yet.

• Ya, mousing over that turns the looking glass blue, and is a CSS thing I thought was cute was quickly got the feedback it's just confusing :) Will change
• Yeah - I agree that I need to add instructions, including how to structure queries, what the keys are for the dataset in a more accessible way than the table below, etc...
• So this is an interesting point - I think it'd be great if an attribute of schemas that we support would be "url" or "uri", and if that's provided, the listing of ./examples/ds001.json would link to its location.

The more I think about this project, the more I think it'd be nice to essentially have an explicit query format exposed through a RESTful API that is data-agnostic. I.e. given a dataset and metadata definition, it should simply wrap the quickly growing datalad search functionality. Looping @jbpoline in for comment.
