Re-integrate the Mix and Match theme for Openchurch 7x

OK I have a pretty decent version working on my local box, still doing some testing, customization but I think that this is going to make it to 7x-1.10

OK I have committed the new OpenChurch Mix and Match theme to dev. It should be functional as it looks pretty good on my box but I will do a full end to end download/install/test when the 2x dev package is updated.

I still need to do some tedious css tweaking and browser testing.

I also have only been testing the skins that I install by default. I need to test page background colors for instance to see if that still looks good.

Did some minor CSS fixing here and there. Updated some defaults and added the mobile responsive stylesheet.

Still need to do some browser testing and will try to figure out how to enable rounded corners by default.

Tested firefox
Tested ie7
Tested ie8
Tested Opera
Tested Mac Safari

Got some CSS fixes and browser-related CSS fixes into dev. There are some subtle differences left such as some pixels in opera/ie but overall pretty good.

The 7x version of mix and match doesn't really have stock rollovers like it did in 6x. Instead it has some kind support for superfish menus which is what we're using. But I had to add in some of my own css for it to work. So I have made the rollovers a neutral gray color instead of keeping them the same color as the parent menu bar. Later on if I or someone else had time, I would just need to play with it and maybe even have to add selectors for each color (black, blue, gray) and make the colors match which wouldn't be too hard. I am just going to go with gray for now for expediency.

Overall it looks really good.
