[PATCH] The default rake task should be set in Rakefile not misc.rake

By specifying the default rake task (task :default => :test) in misc.rake, applications have no easy way to override it. Specifying a default in the application Rakefile will cause both tasks to run, not the new default.

To fix this annoyance, the default should be part of the generated Rakefile where it can be changed at will.
