光盘高尔夫球场的地图（测试版）

此版本中的新功能：Now using internal database that synchronizes with discgolfstats.com. After the first download, course maps are only downloaded again if there has been a change. The internal database will speed the application up an make it less dependent on an internet connection. Added a status notification to make it easier to return to the application. Added some checks to make sure an internet connection is available before tying to access data from discgolfstats.com. Should reduce crashes.
