Updated the project version to 0.2-SNAPSHOT
Improved comment in the build.sbt about the hard dependency on the sbt-git plugin
Make the default theme easier to overwrite

Fixes #2
Moved to version 0.2
Made the default theme example project explicit

This makes sure that any global system default prompt will not win (because explicit project settings override global settings)

Also reamed the two included themes to have names ending in "Theme" because especially the "Default" theme clashed with other Default vals/objects in import scope. The old names were left but deprecated
Made the current project render with a slightly darker color

Fixes #3
