[rule links] reduce visual clutter

[hshoff]

It's great that we added the eslint and jscs links for each rule, but I think there's an opportunity here to reduce the visual clutter a bit for easier reading and skimming. I'm proposing moving the links to a comma separated list at the end of the corresponding rule. I feel it's not too difficult to identify which links are eslint vs jscs, but open to discussion on bringing back the labels.

^ seeing all that space used for a label and a link makes me 😢

I'm down for the line condensing, but I think labelling as "eslint" and "jscs" is critical, especially since there's 0 to N rules that could apply for each.

I battled with that too, but here's how I settled on removing the labels:

• eslint-rule vs jscsRule
• hovering over the link
• we can remove 37 instances of eslint and 36 instances of jscs
• what's the use case where a reader wishes they could get to the eslint rule faster?

hovering isn't a good affordance and doesn't work on mobile :-/

To me it's not about getting to it faster, as much as it's about clearly identifying, at a glance, that we have eslint and jscs rule coverage. The rule names are secondary (but necessary)

There came a point where I was thinking to myself, "I shouldn't have done this by hand"...but it was already too late.
