Add FogAdapter
* Remove yahoo_app_id accessor
* Move verbose attr_accessor to attr_writer as we already have a custom reader
* Remove sitemaps_host from attr_accessors as we have custom methods for both reading and writing
* Fix number helper rounding spec that breaks in Ruby 2
Merge branch 'master' of https://github.com/laurynas/sitemap_generator into laurynas-master

Number helper difference appeared in Ruby 1.9.3
