Update configuration an make logic in order to select that the serial blaster task priority and stack size. From Bob Doiron

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
