@1aurabrown => Help menu tweaks

Fixes #119.

@katarinabatina Attached is a screenshot running in the simulator. It's a bid odd, since I've matched the font sizes and margins to [the specifications](https://cloud.githubusercontent.com/assets/6482926/4614568/7838117e-52e1-11e4-9552-6c3268508eac.png), but the text is still wrapping slightly different from your screenshot. I'm wondering if maybe there is a slight difference between the font files used in the app and those used in Illustrator? In any case, let us know if you'd like anything about this changed.
