Zoneminder - flat theme.

I've loved Zoneminder for years, but find that when I demo it, the minimalist UI inhibits adoption.

@brettsvoid and I have created a flat theme (invoked using http://yourzm/zm/?skin=flat) that we're hoping you'll like.

We've really only copied skins/classic into skins/flat and modified 2 CSS files, but the changes look a lot bigger after the copy.

There's still a lot more that we could do to improve the theme, but just wanted to see how the process works and whether the team like the direction.

Thanks!
