Fix bug #1483185; File - New now erases property lists, variables, and buried procedures.

Fix bug #3146515, which is a stack buffer overflow in PO when printing a procedure with a long line.

Add some function comments.

Fix a bug in the regression test for bug #3146515 that prevented it from running once the bug was fixed.

Add a regression test for bug #3146515, which is a stack buffer overflow when calling PO to print a procedure with a long name to the commander.

Add a menu option to export the current workspace to the screen saver.

Enable stronger compiler optimizations in release builds.

Fix a buffer overrun when configuring the file which the screensaver uses.

Also add some logic to write whatever text was destined for the commander's recall box to the screen. In addition to being a more complete implementation of Logo, this is an inexpensive way of printing out when errors happen, which is very helpful when debugging.
