Few commits

Hey Eddy, love the project. I went ahead and updated the .gitignore file, removed the sizewithfont stuff, and added an animation when deleting a tag. 

I actually left a few animations in there for the tag deletion, right now it just makes scale to 0,0, but the other options are reduce its alpha, move it off screen, and I'm sure theres plenty more depending on what you want to do.

I tried looking at the deletion issue, its very weird to me, I'm not sure why that happens but id like to look at it more in the future.
