Move "Light (Preview)" Theme to the "Light" Theme

- Copies over all changes done in the "Light (Preview)" theme to the
"Light" theme. So the changes done in the preview theme are now the
default.

- Delete the "Light (Preview)" theme as it's no longer needed.

Also:
- Simplify the plugin.properties file to remove duplicated strings.
