Lua: added a message box. messagebox('message'), or messagebox('caption','message'). note that Lua supports concatenation (operator ..) and this function accepts backslash-n for carriage return. It performs word-wrapping if needed. Fixed the Hourglass cursor showing up in some error boxes, instead of the arrow cursor.
