created BluetoothManager and just barely started writing that code.  Also created P2Pmanager, which is just a class at this point. These will be used later for device-2-device communication. Made the settings class serializable so it can be saved as an object to the device. (User settings persist through runs). Upgraded app to API 14...sigh. This was good to upgrade but bad because apparently you can't do any network connection stuff on the main thread of the application so I had to rewrite the DownloadManager with a lot of headaches.  It works right now but there's still some issues. Fix later.
