Support for srcset

[AndreKR]

This PR adds support for <img srcset="...">. The srcset URLs are converted to require()s, just as <img src="..."> is, the descriptors stay untouched.

Would love to have this pulled, when can I expect this?

[AndreKR]

As a workaround I'm currently putting

"vue-loader": "AndreKR/vue-loader#srcset",

in my package.json.

Note however, that I'm not actively monitoring vuejs/vue-loader to pull in updates.

Hi @AndreKR,
thank you for this. We tested it and discovered a couple of issues: your code does not take into account attributes spawning multiple lines, and srcset attributes on source tags (useful for picture elements).

I made a quick review of your code that I submitted as a PR, but I think credit fir this should be yours, so feel free to review them and update this PR.

For all of those that can't wait, see https://github.com/therealpecus/vue-loader srcset branch.

@therealpecus Thanks for the fixes, I cherry-picked your commit into this branch. I found another issue with whitespace within the candidates. I also added a test for all three cases. Please check again.

Hopefully this will speed up the approval process. Thanks for the further review!

Any word on merging this? Thanks.

Whilst this was merged, it doesn't appear to be in any stable version of vuejs loader... I'm still having to use AndreKR's forked version. Any plans?

Any word on how to get this working?
