Upgrade to Maruku 0.7.2

[bhollis]

Maruku has had two maintenance releases since 0.7.0: https://github.com/bhollis/maruku/blob/master/CHANGELOG.md

These are backwards-compatible bugfix releases.

0.7.1 was not backwards-compatible IIRC (or introduced new bugs) but let's give 0.7.2 a try. Would you mind submitting a PR with the necessary changes?

[bhollis]

I've converted this to a pull request. I didn't see any tests that would verify that this new version works the way you'd expect, though - if you have those, let me know and I'll run them.

In the future, if you have problems with Maruku (backwards incompatibilities, bugs) please file issues at https://github.com/bhollis/maruku/issues so we can address them. The intention is for Maruku to follow semver, modulo changes to output caused by fixing broken behavior.

Looks like I'll also have to file a PR to Jekyll because they locked to a specific minor version.

This PR needs to be applied to the jekyll-2-1 branch.

[bhollis]

jekyll/jekyll#2576

[bhollis]

@thomasjo unfortunately I cannot change the target branch of a PR once filed. Would you like me to file a new PR?

[thomasjo]

@bhollis Nah, should be fine as long as the PR is applied with git-am or similar. I'm sure @parkr will sort it out.

[benbalter]

Still interested in the bump? Jekyll-2-1 is now master

[parkr]

I've done this in #82.
