NOTE: Need https://github.com/mdedetrich/xsbt-web-plugin to compile.

This bumps the whole sbt-plugins project to work with SBT 0.10.3 an Scala 2.10.3 while also fixing depreciation issues. You need an bumped version of xsbt-web-container for this to work (since it also needs to be bumped) as well as an updated untyped tipi plugin (https://github.com/mdedetrich/tipi)

Unlike https://github.com/untyped/sbt-plugins/issues/34#issuecomment-25967964, this works for all sub projects of sbt-plugins (including sbt-runtime)
