Add a note about CocoaPods to the README

Add a small note about installing hoedown via CocoaPods.

I created the hoedown spec, because I use CocoaPods extensively in my projects and in the past weeks I really fell in love with hoedown, so I had to add it to CocoaPods/Specs ;)

See: https://github.com/CocoaPods/Specs/blob/master/hoedown/2.0.0/hoedown.podspec

Hi, what are your plans on tagging a 3.0 version? For now I have to work with your 2.0.0 tag (can't set the CocoaPods podspec to git master)
Would be great to have a 3.x tag! Best regards, Clemens

We're looking into it, I'd like to at least do some cleanup and set up a styleguide (#15) before v3.

Ok, in the meantime I will work with the master branch and as soon as you tag a v3 I'll update the CocoaPods spec for hoedown.

Maybe a TODO.md file would be helpful to know what's planned or where others can jump in and help.

Regarding coding style conventions, the tool clang-format helped my team a lot: http://clang.llvm.org/docs/ClangFormat.html
Some styles are built-in (Google, Chromium, Mozilla, etc.) but you can also define your own.

We need to set up coding style, and do some cleanup according to that. I think that's enough for v3.

Wow, that's awesome! @devinus we definitively have to look into it.
