Some layout changes to the replay menu.

Cursor should not blink in read-only.
The path was too similar to the list and thus easy to miss, it has been changed to a 'golden' colour.
A tooltip was added to the path.
The border colour of input fields was changed from white to gold.
The buttons at the bottom of the page are spread evenly.
