Bump sanitize from 2.0.4 to 4.6.3

[dependabot]

Bumps sanitize from 2.0.4 to 4.6.3.

Release notes

Sourced from sanitize's releases.

4.6.3 (2018-03-19)

• CVE-2018-3740: Fixed an HTML injection vulnerability that could allow XSS.

  When Sanitize <= 4.6.2 is used in combination with libxml2 >= 2.9.2, a specially crafted HTML fragment can cause libxml2 to generate improperly escaped output, allowing non-whitelisted attributes to be used on whitelisted elements.

  Sanitize now performs additional escaping on affected attributes to prevent this.

  Many thanks to the Shopify Application Security Team for responsibly reporting this issue.

4.6.2 (2018-03-19)

• Reduced string allocations to optimize memory usage. [@​janklimo - #175]175

4.6.1 (2018-03-15)

• Added support for frozen string literals in Ruby 2.4+. [@​flavorjones - #174]174

4.6.0 (2018-01-29)

• Loosened the Nokogumbo dependency to allow installing semver-compatible versions greater than or equal to v1.4. [@​rafbm - #171]171

4.5.0 (2017-06-04)

• Added SVG-related CSS properties to the relaxed config. See the diff for the full list of added properties. [@​louim - #161]161

• Fixed: Sanitize now strips null bytes (\u0000) before passing input to Nokogumbo, since they can cause recent versions to crash with a failed assertion in the Gumbo parser.

4.4.0 (2016-09-29)

• Added srcset to the attribute whitelist for img elements in the relaxed config. [@​ejtttje - #156](https://github-redirect.dependabot.com/rgrove/sanitize/pull/156)

4.3.0 (2016-09-20)

• Methods can now be used as transformers. [@​Skipants - #155](https://github-redirect.dependabot.com/rgrove/sanitize/pull/155)

4.2.0 (2016-08-22)

• Added -webkit-font-smoothing to the relaxed CSS config. [@​louim - #154](https://github-redirect.dependabot.com/rgrove/sanitize/pull/154)
• Fixed: Nokogumbo >=1.4.9 changed its behavior in a way that allowed invalid doctypes (like <!DOCTYPE nonsense>) when the :allow_doctype config setting was true. Invalid doctypes are now coerced to valid ones as they were prior to this Nokogumbo change.

4.1.0 (2016-06-17)

• Added a new CSS config setting, :import_url_validator. This is a Proc or
  other callable object that will be called with each @import URL, and should
  return true to allow the URL or false to remove it. [@​nikz - #153](https://github-redirect.dependabot.com/rgrove/sanitize/pull/153/)

4.0.1 (2015-12-09)

• Unpinned the Nokogumbo dependency. [@​rubys - #141](https://github-redirect.dependabot.com/rgrove/sanitize/pull/141)
