Add support of SmartSymbols

[ghost]

Hello there! Could you add the support of the SmartSymbols extension, I really like it much 😍

Thanks!

I'd bring over more of those plugins, but it is always a pain porting them over here. I wish this plugin would drop ST2 moving forward, then I could just add pymdown-extensions as a dependency. But as it is now, I have to port them over and ensure that anything I bring has Python 2.6 support, which pymdown-extensions doesn't do out of the box. It's why some of the extensions here are behind .

I may be able to get this in. I'm working towards helping to drop ST2 support and pulling all the stuff via dependencies.

This is working on the dev branch now, but that branch is unstable right now as I am refactoring and changing how things work. But this will definitely be in 2.0.
