v2.0.0

v2.0.0

• Small refactor/code cleanup
• getInventory call now uses node-steam-inventory-api-ng to do its inventory calls. Custom parameters for the inventory API can also be set in the constructor
• getItemsForApp doesn't need a format parameter. Instead if compactValue is true, it is assumed that format should be compact for the SteamApis.com request. If compactValue is any other value. format will still be compact and compact_value will be set to compactValue
