Set "errdhotfocus" to a higher contrast color combination. Yellow is barely
visible on lightgray. The cursor stands on the the focused hotkey. If the
cursor is an underscore, the high contrast is obviously needed. If the focus
is a full box, it normally inverts both the background and the foreground, so
poor contrast remains poor. Red on lightgray is consistent with other colors
of the skin.
Set "menutitle" to yellow on blue. Otherwise, the title is not
distinguishable from the menu entries. Both "parent" skins, default and
xoria256, use distinctive color for the popup menu title.
Set "editrightmargin" to the same color as the panels. White on blue is
extremely distracting in contrast to black background to the left of the
margin.

Set "disabled" background to "lightgray" for consistency with the dialog
background. The inconsistent background can be seen in the file search dialog
with an empty search string.
The hotkeys in dialogs were impossible to distinguish from other text. Make
them red for consistency with the buttonbar.
Show changed lines in diffs in black on cyan. Blue on cyan is hard to see,
such color combination is not used elsewhere in the skin, which promises
"good contrast".
