[Dvdauthor-developer] dvdauthor-633

adds support for cells.  this should be considered bonafide ALPHA code,
and I expect there to be some bugs.

dvdauthor will automatically detect two VOB's with the same filename and
treat them as a shared source, UNLESS you specify any buttons.

If you want a finer grained control over the VOB/cell creation, other
than just specifying chapters, then you can manually specify cells, as:

<vob file="FOO">
<cell start="x:y" end="x:y" [chapter="1"] [pause="Z"]> CELLCOMAMND;
</cell>
</vob>

start and end times are as expected.  if you omit 'end' it assumes the
end of the VOB.  if you omit 'start' it assumes the end of the previous
cell, or the beginning of the VOB if it's the first cell.

CELLCOMMAND must compile to a single VM instruction; however since there
is no optimizer in place yet, then stuff like

if (g3==g4) g5=g6;

is not possible, since the compiler currently treats those as 2
comamnds.

Anyways, please test it out if you want cell support and let me know how
it works for you.
