Small cleanup

Remove unnecessary init — since [super init] on UIView subclass
 calls initWithFrame:CGRectZero which we already override.

Also add QuartzCore import to a file where we use Quartz
(though Xcode5 doesn’t seem to complain even without the import...)
Replace some magic floats with CGFLOAT_MAX

Also include Foundation.h header everywhere.
Make DetailView protocol interface more abstract

Can now pass a third piece of metadata — whether the
piece of content has “moderator” annotation.
Layout improvement

Increase spacing between header and body in detail view
Fix missing avatar bug for non-Twitter collections

Profile object would not be returned in the delegate method
unless a Twitter handle was present. This fixes that.
