1) The selected text colour is now easier on the eyes
2) The output log will always scroll to the end when you enter a command
3) The output log will now correctly scroll to the bottom when it is first opened (it forces the scrollbars to always visible to avoid the horizontal scrollbar being able to move the vertical scrollbar up slightly from the bottom of the log)
