v.3.9.5

This release fixes a major bug with the url-loader options (#262), as well as updating most of the dependencies. The most major ones are:

• react and react-dom updated to 16.2
• react-hot-loader updated to 3.1.3
• eslint updated to 4.12.0, with all surrounding plugins also updated
• react-router-dom updated to 4.2.2

This release is also the last one in the v3 lifecycle. The next release will start the v4 lifecycle, in which I plan to implement Prettier, create a separate branch for a Redux integration. In v4, I also plan to test how Typescript suits the project.
