'play war' fails when the war name looks like the play project

[Rob Dawson]

In the 1.0 branch the updates to the 'play war' to stop creating the war in a subfolder of the project also prevents the play war command from creating a war with a name that looks like the play app.

i.e if your porject is:
~/play/my_proejct

you are prevented from creating
~/play/my_project_war.

The guard on line 467 of play is the cause.

The code is something like:
  if war_path.startswith(application_path):
   print "~ Oops. Please specify a destination directory outside of the application"
   print "~"
   sys.exit(-1)
