URL Manager is now a singleton object rather than a class with static members
All URL related classes have been refactored into package cz.brmlab.yodaqa.provider.url
URL sets are now stored in dict map json object instead of a 2D array.
All URLs have a key associated with them located in cz.brmlab.yodaqa.provider.url.UrlConstants, where the constant acts as both the System.property override (the CLI -D flag) and the key in the json dict map. This also keeps the set of urls easy to extend w/o breaking existing functionality, as you can add new urls into the json dict map, and just add a new constant in the UrlConstants class that any new classes can depend on.
