I introduced a parameter to make the script more JIP/MP firendly

nul = [JIP] execVM "intro.sqf";

JIP - number, time in seconds
- if negative the intro will be played for all JIP players regardless the time they join
- if is bigger than 0, players joining after the amount of seconds specified will not see the intro

Examples
> INTRO will be played for all JIP players regardless of joining time
nul = [-1] execVM "AL_intro\intro.sqf";

> INTRO will be played for all JIP players if they join in the first 10 seconds after mission starts
nul = [10] execVM "AL_intro\intro.sqf";

* Script clean up
* Minor tweaks
* Added a new boolean parameter that, as in my movie maker script, will tell if the current camera shot is the last one or not
* Everything else stays the same, for more info see the video tutorial

v1.02
- changed condition for script to run to avoid launching it on HC
- using global variables instead of public variables to control intro progress

v1.01 Changelog:
fixed: when on MP/dedicated with many players camera would jump between player view and camera shot, now should work fine. Tested on dedicated but not in MP. Any feedback would be greatly appreciated. Thanks!
