Remove delay at run time caused by skipped lines

[exodrifter]

As noticed in issue #41, the number of init statements that were executed before the first block effected how long it took until the first line of dialog was rendered on the screen. Similarly, whenever a line that doesn't need to be rendered gets skipped, Raconteur waits until the next update cycle before moving to the next statement. This causes a noticeable delay to the player, especially when multiple statements are skipped in a row.

Remove the delay caused by the RenPyDisplay.cs or RenPyViewBasic.cs scripts waiting for the next update loop when a line is skipped.
