Add status bar. #10

Closed allanlw closed 7 years ago

A status bar on the top VGA line allows the kernel to display information to the user without it being intermingled with usermode text. For now, it simply displays the name of the currently scheduled program, or the text "{}" for the idle thread.

The status bar is displayed with a yellow background, because people like colors.

This is cool, but it conflicts with my long term goal of taking IO (such as VGA) out of the kernel.
