New type of ResourceBundle - NetworkResourceBundle - This bundle grabs its resources over HTTP from a root URL rather than from a local jar file. To make use of this, we need a way to put all the contents of the bundle into an appropriate directory instead of a jar, including its metadata, so some new Bundler Tasks were created to do this. Finally, allow tile set trimming to be done to a non-raw image format through passing an optional imgFormat parameter. If no parameter is passed, it'll default ot the old behavior of using raw/FastIO. Note that to use network bundles, you can set the set_type in the resource manager.properties file. (e.g. "resource.set_type.tilesets = network") If no set_type is set for a resource set, it defaults to a normal FileResourceBundle
