Signed-off-by: NJosé Valim <jose.valim@gmail.com>

application generation: --skip-testunit and --skip-activerecord renamed to --skip-test-unit and --skip-active-record respectively

Reason is their proper spellings are "Test::Unit" and "Active Record".
Option names and descriptions have been revised, as well as some method
names and minor details here and there.

* AS::Notifications#instrument should not measure anything, it is not its responsibility;

* Adding another argument to AS::Notifications#instrument API needs to be properly discussed;
