callLater for thread safety

[aferust]

Dear Adam,

I asked if minigui is thread-safe, and you said that you don't know almost a year ago. I implemented it please do your tests.

import std.concurrency;

import arsd.minigui;

LineEdit text1;

void main() {
    auto window = new MainWindow();

    auto exitAction = new Action("E&xit");
    exitAction.triggered ~= { window.close(); };

    window.statusTip = "D ROX!";

    auto vl = new VerticalLayout(window);

    text1 = new LineEdit(vl);
    auto button1 = new Button("Hmm", vl);

    button1.addEventListener(EventType.triggered, () {
        spawn((){
            // callLater(delegate(){ // uncomment me for thread safety
                text1.content = "Hmm";
            // }); // uncomment me for thread safety

        });

    });

    window.loop();
}

Did you know you can use UFCS on delegate literals?

Hey c'mon. You took my chance for contributing :-D.

yeah this came up because i wanted to do the integrated terminal emulator thing in terminal.d... and to retrofit old terminal code, i put the gui in a separate thread. (which i now kinda regret, i should have just had them communicate through a pipe but meh oh well)

this meant i needed some way to run stuff like menus in the appropriate thread and thus that little function was born. kinda hacky but seems to work.
