#664 Add a "high contrast" cloudy theme.

[Jeff Adams]

I wanted a high-contrast cloudy theme, because I liked
the cloudy theme, but my grandfather's eyesight isn't
what it was. So I created one. It probably isn't
perfect so someone more familiar with CSS than I should
proof-read it.

I started with a copy of the cloudy theme, and made
tweaks. I changed opacity to 100 almost everywhere and
tweaked colors so that most fore/background color
combinations pass the color brightness and color
difference checks on
http://juicystudio.com/services/colourcontrast.php
(a php script that shows the colors and calculates the
difference and brightness per the W3C's formulas).

In order for this to correctly color the tabs (Personal
Facts and Details, Notes, etc) the tabswitch javascript
in individuals.php will have to be changed similar to
what I described in the "bug" I entered.
