v1_1_24: various patches for bugs 🐛

This Release introduces various fixes:

• (beta) #13

thread-safe: A new thread is added to the windows form to select the file. This should avoid the freezing of the canvas.

better-naming: the btn is now changed to a more understandable name select_file

• #3

now the error is catched and error is thrown by giving back a failure. So for now we cannot run two instances of script-sync rhino but at least this case is handled.

try
{
    TcpListener check = new TcpListener(IPAddress.Parse(Ip), Port);
    check.Start();
    check.Stop();
}
catch (Exception e)
{
    if (e.Message.Contains("Only one usage of each socket address"))
    {
        RhinoApp.WriteLine("Error: there are two instances of Rhino running script-sync, only one is allowed.");
    }
    else
    {
        RhinoApp.WriteLine("Error: " + e.Message);
    }
    return Rhino.Commands.Result.Failure;
}

• #7

now the error has a traceback that shows the line and module generating the error as well as all the traceback log, this is an example:

1. Error running script (PythonException): script-sync::Error in the code: invalid syntax (my_module.py, line 3)
Traceback (most recent call last):

SyntaxError: invalid syntax

• #8

Now the output parameters do not stick anymore between the recomputation of the component. This is done by emptying the locals dict in the exec() function.

• #12

The output nested lists now are automatically converted to GHTrees but only for 2 level of depth
