Updated changelogs and release notes in preparation for the 7.2 release.  Still need to do a little more before the release

Fix Bob's name in as many places as possible; Make sure that Bob is an author in as many files as I can think of (might be missing a few)

examples/touchscreen:  Add a configuration option to indicate that there is or is not an architecture-specific initialization function

apps/netutils/ntpclient:  Add a primitive NTP client.  Initial checkin is untested and probably incomplete

Back out part of  610e2aa0c224e2936fe8009ef4a2351ce607067a: Need to be able to select USB console devices when there is no /dev/console enabled.  Noted by Librae

apps/system/usbmsc:  Back out kludge that is no longer needed with the recent fix to the USB MSC class
