Many things done:
- MainActivity scans the smartphone services for right ble support and forces to turn bluetooth on.
-> When everything is okay: Scans for near devices (with rssi) and finds broadcasting ones.
-> To reach that I had to remove the whole Tab-Environment and replace it with a List-Environment,
that marks known bottles green (else they are black)
-> but there is no saving function for the bottle, so that's something important to do
--> save it in file, but remember function of geo-location, that will maybe clarify exactly the
last position of earlier users, so we maybe need hashing or an internal passphrase

- with onClick on Item in list you will get to the BottleDetails, where you will get directly connected with the device
-> some information are listed there (mac, name, provisional id)
-> and an expandable list, that lists known services of the device (at the moment, there is only the bottlemail service
that I could interpret as useful- so I hardcoded its characteristic that sends "Bottlemail. Hello..." to BMAIL_HELLO)
-> you can disconnect (fast) and reconnect again (very slow, up to 20seconds, be patient)
had to add some files to commit, everythings the same
