fix: Make class static attributes compile to global Workshop variables

[CactusPuppy]

Previously, class static attributes were incorrectly initialized as player variables in the Initial Global rule, resulting in an error.

Example:

class Example {
    public static Number n1 = 1;

    public constructor() {
        n1++;
    }
}

playervar Example myExample;

rule: "test"
Event.OngoingPlayer
{
    myExample = new Example();
}

Previous output:

variables
{
    global:
        0: _classIndexes
    player:
        0: n1
        1: myExample
        2: _extendedPlayerCollection
}

// Extended collection variables:
// player [0]: _new_Example_class_index

rule("Initial Global")
{

    event
    {
        Ongoing - Global;
    }

    // Action count: 2
    actions
    {
        Set Player Variable(Event Player, n1, 1); // !! THIS IS INVALID !!
        Set Global Variable At Index(_classIndexes, 0, -1);
    }
}

rule("test")
{

    event
    {
        Ongoing - Each Player;
        All;
        All;
    }

    // Action count: 5
    actions
    {
        Set Player Variable At Index(Event Player, _extendedPlayerCollection, 0, Index Of Array Value(Global Variable(_classIndexes), 0));
        Set Player Variable At Index(Event Player, _extendedPlayerCollection, 0, If-Then-Else(Compare(First Of(Player Variable(Event Player, _extendedPlayerCollection)), ==, -1), Count Of(Global Variable(_classIndexes)), First Of(Player Variable(Event Player, _extendedPlayerCollection))));
        Set Global Variable At Index(_classIndexes, First Of(Player Variable(Event Player, _extendedPlayerCollection)), 1);
        Modify Player Variable(Event Player, n1, Add, 1);
        Set Player Variable(Event Player, myExample, First Of(Player Variable(Event Player, _extendedPlayerCollection)));
    }
}

New output:

variables
{
    global:
        0: n1
        1: _classIndexes
    player:
        0: myExample
        1: _extendedPlayerCollection
}

// Extended collection variables:
// player [0]: _new_Example_class_index

rule("Initial Global")
{

    event
    {
        Ongoing - Global;
    }

    // Action count: 2
    actions
    {
        Set Global Variable(n1, 1);
        Set Global Variable At Index(_classIndexes, 0, -1);
    }
}

rule("test")
{

    event
    {
        Ongoing - Each Player;
        All;
        All;
    }

    // Action count: 5
    actions
    {
        Set Player Variable At Index(Event Player, _extendedPlayerCollection, 0, Index Of Array Value(Global Variable(_classIndexes), 0));
        Set Player Variable At Index(Event Player, _extendedPlayerCollection, 0, If-Then-Else(Compare(First Of(Player Variable(Event Player, _extendedPlayerCollection)), ==, -1), Count Of(Global Variable(_classIndexes)), First Of(Player Variable(Event Player, _extendedPlayerCollection))));
        Set Global Variable At Index(_classIndexes, First Of(Player Variable(Event Player, _extendedPlayerCollection)), 1);
        Modify Player Variable(n1, Add, 1);
        Set Player Variable(Event Player, myExample, First Of(Player Variable(Event Player, _extendedPlayerCollection)));
    }
}
