update: Updated database for records
update: Updated database for records

* New column group_id was added into record table and database group_record was created. It just holds actual
index of latest group_record.

* I had to change storage of text file for records because older version of android do not support path DOCUMENTS
so I rerouted it into DOWNLOADS. I know that it is not the best solution but best from all others (PICTURES, MUSIC and so).
