Added Level-1 to 10 for sublime-levels support

Douglas Crockford had the idea of scope context coloring for JavaScript and added it to JSLint: https://plus.google.com/+DouglasCrockfordEsq/posts/FzKnHk96m2C
Alexander Mazurov then created the sublime levels plugin: https://github.com/mazurov/sublime-levels
I love the idea, but the I find the theme he uses horrible!
So I simple enhanced my favorite theme Flatland.
I like the result and would like to share it with you.
