I have converted the other two triggers to use time index info
as well. The changes make the use of these three triggers somewhat
incompatible with <=0.4.3 but if have decided not to flag the
binary format incompatible as this only affects maps which use
the triggers with values other than -1 or 0.

(I have some more incompatible changes planned anyway, but those
will have to wait for 0.4.5.)

Upgrading your maps to 0.4.4 should be a simple matter of loading
the maps into CoMET and adjusting the trigger data for Turn triggers
(which are now called Timer). Shop Owner and Unit Owner need only
be fixed if the Turn parameter is used. The new numbers are
calculated using the formula:

time index = (turn number - 1) * 2 + (player number - 1)

Turn 1 is time index 0 or 1, turn 2 is 2 or 3, etc.
So if you want to execute during player 1's movement phase on turn
4, you'd have:

time index = (4 - 1) * 2 + (1 - 1) = 6
