Changed close buttons and find box.

1 - Made the close buttons a brighter red.
2 - Made the hints more visible
3 - Put the find and replace boxes in line with everything else. This is where the text-field icon is used. Note that find in file still doesn't line up and it's that way in the default scheme too.
