Feature/improve sidebar

[jeremyckahn]

Hello, I love Minami and I would like to contribute to it!

This PR fixes a bug:

• It prevents particularly long names in the sidebar from breaking to the next line.

And it adds a feature:

• It shows class members in the nav. This is purportedly fixed by Add members to nav #13, but it doesn't work for me.

Thanks for making a great JSDoc theme!
