Website and Swedish localization

Added the website yesterday. Honestly, I could not have achieved this by myself. It looks great in my view. Today I've added Swedish localization. It was a bit back and forth but turned out good in the end. Now Todo is more or less ready for external beta even though I'm just starting todo (I hope at least that I'm able to install the internal beta build on my sister's phone). I also started a side project called skrivhjälp.se, let's see how it goes. Off to celebrate birthdays of sister and mum in Sala, so not that much vibing today.
