added Transparent White as a theme option

Very similar to the Transparent Black but this makes some readability improvements based on several of the broadcasts backgrounds not working well with grey text. Also shows the VIPs in a nice subtle way (shape/outline of the avatar)
Update version number so it distributes.
Gotta update the changelog for a new version too.
Merge pull request #15 from pironic/master
