mcomaster puppet module should configure initscript defaults

This commit extend the mcomaster puppet module to configure
the initscript parameters.

Also this fixes that the mcomaster_port was not working,
because it was commented on sysconfig/mcomaster template.

example usage:
class {'mcomaster':
  mcomaster_port         => 8080,
  mcomaster_env          => dev,
  mcomaster_use_thin     => 1,
  mcomaster_thin_use_ssl => 1
}
mcomaster puppet module should enable service.

The mcomaster should enable and ensure the service
mcomaster is running.

This commit makes this possible.
