Pre-release v0.0.5

Some not big changes have been incorporated, including making the app more orange (Hacker News!) and adding a open-in-Safari button.

I'm trying to make more time to spend in this project, so I hope that I'll be able to fix some more bugs, add a bit more features and call it v0.1.0 in a not-so-far future. Every bug report helps, including things that are so trivial that a person can download the binary and find it right away. (I use the app daily, so it's hard for me to find out very obvious bugs because I'm so used to it.)
