- removed I_MSTime entirely after checking how the wipe code actually…

… works.

Since this calls I_WaitVBL, which resets the frame time, it was essentially just like calling a real-time timer anyway and nothing in it required a specific 0-timepoint.
The same applies to the ZScript interface. All it needs is a millisecond-precise timer with no semantics attached.
