[$40] Update registration confirmation design

[jmgasper]

@atelomycterus - We had to update the links to be absolute instead of relative, just FYI.

We also have a new design with some changes from Topcoder. Can you make these changes please?

@jmgasper What url should be used for resend the activation email?

Please correct me if I am wrong. For the following links:
Learn - https://www.topcoder.com/community/learn
Gigs - https://www.topcoder.com/gigs
Competitive Programming - https://www.topcoder.com/community/arena

Thanks!

@atelomycterus - Those links look good. For now, you can leave the resend link unimplemented. I'm still trying to find out how we're going to implement that one, thanks.
