The style for the search bluetooth devices dialog is now configurable trought the DeviceListDialogStyle class. The bluetooth connection can be now stopped from the Activity that extends BaseBluetoothConnectionActivity.
Modified in order to check the connection with the bluetooth without showing the toast to the user.

Fixed a bug with the styling class of the bluetooth search dialog. Added a new base class (that extends the existing one) for the child activities which only send commands to the arduino board and do not want to receive any message from it.
