Fix for ./dist/blog initialization issue (#48)

When I went to create a blog for the first time, it kept throwing an error due to the fact that ./dist/blog did not exist. The recursive argument in the fs.mkdirSync function should have created it, but didn't. With this change, it now works on my system.
