Subject: Change the way Timestamp stores its data.

Instead of storing milliseconds and frames (which causes rounding errors,
and causes ambiguity in how a given time is stored), we now do things
differently: We store a number of seconds, and frames. To make sure that
we can still handle milliseconds accurately, though, we change the
framerate to the least common multiple of the original framerate and
1000. So 60 becomes 6000, and 44100 becomes 441000. There are no visible
changes for client code, except for the increased accuracy.
