Change checkRateLimitStatus function

-  RateLimitStatus limit =
twitter.getRateLimitStatus().get("/application/rate_limit_status");
chang to:
+  RateLimitStatus limit =
twitter.getRateLimitStatus().get("/followers/list");
Addtionally, delete code:
-    usrCounter++;
-    if (usrCounter %100 == 0) {
-     try {
-      Thread.sleep(600*1000);
-     } catch (InterruptedException e) {
-      e.printStackTrace();
-     }
-    }
