Publish new version to crates.io

[SSheldon]

The last version of rss was published 8 months ago! There have been some nice improvements since then that haven't been published, including:

• updating from quick-xml 0.14 to 0.17
• removing failure
• the ability to disable the builders feature

Could a maintainer tag and publish a new version?

When the next version of rss is published, I'd also love to see a new version of atom so that both crates are off of failure and have the builders feature. But I can file a separate issue on atom them :)

I'm not sure which version should be, 2.0.0 or 1.9.0? @rust-syndication/publish

Here's my assessment if it's useful:

• the crate was updated to the 2018 edition of rust, which might raise the minimum supported rust version? I'm not aware of this crate advertising a msrv, and I don't think there's a consensus that this must be considered a breaking change
• the value of Error::Xml was changed to no longer be a failure::Compat, but it's still a type that implements Error, so realistically I doubt this is likely to break real world code. This type has been changed in the past without requiring a major version bump.
• ITunesCategory::subcategory no longer returns a reference to a Box
• quick-xml and url were updated, but they aren't really public facing, except their error types?

To me, the biggest thing to consider there seems to be ITunesCategory::subcategory, but even that doesn't seem worth a new major release. So I think a 1.9.0 is justifiable.

1.9.0 sounds good to me, I will release a new version in two days, feel free to show your opinion.
