Devstack should be DevStack and Openstack should be OpenStack in headings

[Pradeep Kumar Singh]

On page http://docs.openstack.org/developer/heat/getting_started/on_devstack.html , heading "Heat and Devstack" should be "Heat and DevStack" so that use of word "DevStack" is unified at all place.

On page http://docs.openstack.org/developer/heat/getting_started/on_fedora.html , at some places there is word "Openstack".
I think this also needs to be "OpenStack" so that "OpenStack" is unified at all places.
