Theme customization options

[bkaradzic]

I found a few things I wanted to change with theme, but I couldn't do it via config file:

• I found default width too narrow, and wanted to change it, so I modified main.scss $wide-size, $narrow-size, and $spacing-full.

• Number of recent posts is hard-coded to 5. My page has low number of posts, and I wanted to see them all there.

• Roboto font has some issue with Serbian Latin characters, so I had to change font. But it would be nice to have a few font options.

• I wanted to add license to footer, so I had to modify footer.html.

These are just suggestions, I'm fine with changing things in theme, and having customized copy of it in my repo. I'm mentioning it in case you are looking for feedback.

This is my home page https://bkaradzic.github.io/ with these changes I mentioned above.

I found this theme to be perfect for my needs. Thanks!
