Use tabs consistently instead of spaces for indentation

Dear Weston,
You're right about the spaces instead of tabs for indentation, and removing the space before the colon. I'm going to fix this now.

I've also scanned the theme with the VIP Scanner and the WordPress Coding Standards sniffer. I also noticed that the VIP standards require escaping values as they're being echoed, instead of earlier.

Thanks a lot for looking at the theme.
