Important milestone: session timeout handled gracefully.  Activity runnables now reauthenticate if the stored auth_token has expired.  This fixes the single most common crash problem.  Code follows this model:

    getHoldsRunnable = new Runnable() {
        public void run() {
            try {
                holdRecords = accountAccess.getHolds();
            } catch (SessionNotFoundException e) {
                try {
                    if (accountAccess.reauthenticate(HoldsListView.this))
                        holdRecords = accountAccess.getHolds();
                } catch (Exception eauth) {
                    System.out.println("Exception in reauth");
                }
            }
        }
    }

At the same time,
* removed obsolete exceptions
* added support for Intellij IDE
