Consider adding fetch to eventbrite_object.rb

[monkseal]

First of all, great gem

Was wondering if you had considered adding a method to eventbrite_object api that would delegate to Hash#fetch?

This could be handly if I do something like:

if eventbrite_event.fetch('logo', {})[:url].present?
...
end
