Synopsis: Move the timestamp smoothing code in the base video renderer
           to a separate class in common/util.

Overview: The base video renderer uses code to smooth out timesyncs.
           There are several good reasons for moving this code to
           a separate class and putting the class in some common
           module: a) other datatype renderers can then use it; b)
           it's easier to unit test; and c) makes it clearer when
           we modify this code for TrickPlay purposes. Right now, I've
           added this to common/util, although it arguably could go
           into datatype/common/util as well. However, I could see
           some applications outside of datatypes that might be
           able to use this as well.

           This diff creates a class with this code and places
           it in common/util. It also adds a unittest for this
           class using the existing unittest framework (which ROCKS,
           by the way - this is the first time I've added something
           to it, and it's very cool).
