Code editor 2: Global functions that use instance variables show them all in global color

[KormexGit]

Description

If you have a global function that uses instance variables, either built in or user defined, CE2 colors them as if the variables were put directly in the script and not inside a function. As a result, they're all in global variable color.

Steps To Reproduce

Define a function that sets instance variables, either built in ones or your own.

These are best assumed to be global variables, unless the function is called from an instance, in which case the scope belongs to the instance, rather than the global scope.

These should be instance variables... not globals...

[zreedy]

These variables are now marked as "Instance Variables". This is persistent event in cases where these are globals such as the example below.

/// Script1

function test() {
    wow = 1234;
}

test(); // No other calls

If this is not acceptable we can kind of intuit if a variable is global by checking the CallingContext's ParentContent to see if it's global but this still would not be a perfect solution. For now the heuristic is that instance variables are highlighted as globals if LocalContext.Type is Script and SelfContext is Global.
