General Theme

1. A huge issue that I ran into while making this theme is that the local website didn't reflect CSS updates until I hard reset my browser. For some reason, no matter how I tweaked settings in the development.rb and application.rb, it consistently cached every version of my CSS, so that I had to empty my cache every time to see updates.
If we can make it behave like normal Ruby on Rails where the website reflects CSS changes on normal refreshes instead of requiring a full hard refresh, that will save us a lot of time. I'm not sure how to make this fix though.

2. I find slim slightly unnecessary. Personally, I find nothing wrong with HTML and I think most of the annoying or inefficient stuff in front-end web design lies with CSS. Luckily for that we have the foundation grid system and the base styling you've pre-installed. HTML in and of itself is not too bad, and a very common language. I think building the website and updating it using HTML instead of Slim will make the process far easier for me and anyone in the future who's more vanilla-inclined.
