Update .gitignore

[mattxwang]

This PR moves over the changes from #1112, namely making the .gitignore more descriptive and bringing it to parity with the recommendations from Jekyll.

LGTM, with a minor suggestion for improving the accuracy of a comment.

BTW, I think it would be good to include proposed CHANGELOG updates in PRs, so they can be reviewed too.

Perhaps the theme docs should mention .gitignore somewhere?

That sounds like a good idea to me! I can do this for all future PRs that I author as well. In this case though, I don't think we should include this in the changelog; this isn't a user-facing change (the .gitignore is not bundled with the theme).

As a result,

Perhaps the theme docs should mention .gitignore somewhere?

Since this isn't user-facing, I'm not sure if it's relevant; or, did you mean as a "here are defaults we recommend"? I'll open a similar PR in just-the-docs-template, which might serve as a better place for that to live in.

Many existing users of JTD may have an outdated .gitignore, and aren't using the template, so they probably wouldn't notice any comments about it there.

One way to draw attention to it might be to update the template for submitting JTD bug issues. In general, I tend to give low priority to issues that don't include a link to a repo where I can see the Gemfile.lock – the issue template could ask for that instead of the (usually irrelevant) info about desktop and smartphone versions, mentioning the recommended .gitignore.

Great idea! I need to write up a few of the items we've discussed anyways, so I'll tag that on to my list of repository improvements. I agree that the current set of issue templates leaves some things to be desired.

Have opened #1346!
