Roadmap update #7

In this update I'm adding Kanban boards, gave the UI a facelift and made project deadlines optional.

1. Kanban boards were long requested feature as being so simple to use and the best at giving you a general overview of the state of your projects. You can now access them in Projects' todo lists.

2. UI facelift
   Made the navbar minimalist and updated the colors on the background. It's important for me to have welcoming colors so I finally decided on this beige-brown faded color. I'm missing the dark theme so that is schedule for the next few weeks.

3. Optional project deadlines
   A lot of projects have no deadlines in sight. Especially when starting something new and exciting we've never done before. So I made project deadlines optional.
