Automatically enables the ignore whitespace option on Bitbucket PRs and commits
Bitbucket does not current offer a way to set the "Ignore Whitespace" setting as your default option when reviewing pull requests and commits. It's an incredibly useful option to have on when viewing side-by-side diffs but neither your Bitbucket account, nor browser local storage, will save you preference to enable it.
That's what this extension does - while enabled, any Bitbucket.org pull request or commit will have the "Ignore Whitespace" option enabled by default. This also applies to the "new PR experience" that Atlassian are rolling out via Bitbucket Labs.
