devlog #6 - more taskbar stuff

i decided that it’s probably a good idea to be able to see what apps you have open, so i implemented a little window list in the status bar. it’s pretty rudimentary - it just makes an element for each open window and updates any time a window is added or removed. eventually i’ll get around to adding window logos and context menus that let you close and minimise windows from the taskbar but that’s a bit advanced for the minute.
