Play only starts in Prod mode when using the play2:run goal

```
[play] [info] play - Application started (Prod)
[play] [info] play - Listening for HTTP on /0:0:0:0:0:0:0:0%0:9000

Everything seems to be working well except for being able to run the 
application in Dev mode. Is this possible without the Play SBT plugin?
