Initial stylus conversion

I went ahead and compiled the `typeplate.scss` file to check the diff against the resultant css from my own `typeplate.styl`, yielding no differences, besides line endings and tag grouping.

There's no concept of placeholders as of yet in stylus, so I used function so we don't have extra classes. Also, there's no separation of mixins or functions, so some of the functions had to be renamed in order to compiled correctly (but they should make sense).

As for stylus conventions, you actually don't need to prepend variables with the `$`, nor do you need colons following attributes (`width 50px` == `width: 50px`), but I opted to leave them in to make it a little more understandable. I'm sure there are more cool parts of stylus that were lost in translation, but I wanted to get the base file working correctly.
