Fix list indents

[baltitenger]

Indent all lists a uniform amount, and also support items with multiple paragraphs.

Fixes #107

[cpuguy83]

Can you add a test case along with a before/after example?

[cpuguy83]

This is also failing the existing test cases:

Sorry, I didn't notice you had tests.

Note that this pr slightly changes the rendering of all list types (unordered, ordered, definition), so while I can update the test cases, you should check if you're happy with the new rendering. Basically, now all of these use an indent of 5.

Current master generates:

If this is ok, I'll just update the tests to match current rendering.

[baltitenger]

Hmm, were there no tests for regular lists before?

[cpuguy83]

It's possible there weren't tests specifically for it.

[baltitenger]

Oops, didn't know it had to be formatted. Updated the PR.
