Fix issue with how Android logging is handled.

- Replaced standard Android logging Handler to avoid Android issue with only logging Level.INFO -> Level.SEVERE log records.  
- Moved logging Handler initialization to AndroidHarness instead of in JmeSystem so logging in AndroidHarness and app startup could be logged.
