Move to Play 2.1-07132012.

Note that the `sbt-play-*` projects have been freshened also.

Previously we built using 2.1-06142012 but the artifacts included Play 2.0.3. This has been fixed. At least there is clarity about which version is in use. Previously, it might have been expected that the listed snapshot was used.

This nightly is the last nightly of Play 2.1 branch released for SBT 0.11.3 and Scala 2.9.1.

We cannot move forward again until Scala 2.10 and Play 2.1 are released. This will involve a SBT 0.12, Scala 2.10, Play 2.1 combined version update.

IN CASE HUBRIS TAKES HOLD AGAIN: Repeat, the next version update must be the SBT 0.12, Scala 2.10, Play 2.1 combined  update. There is no point revisiting this until Scala 2.10, Play 2.1 are released and final.

SBT is not fit for purpose.
