Since the only implementer of this is the LocationBarView, and all the classes
in question are views code that know about LocationBarView (it's in the same
source directory), it seems like we could just add these functions directly to
that class and then have the classes that access them take a LocationBarView*. 
Sure, that makes it less explicit which pieces of the LBV those classes will
need to access, but I think having fewer delegates/interfaces is worth that
tradeoff.
