Display scanned records

### Rodyti įrašus išsaugotus duomenų bazėje
Nuskenuotų prekių sąrašą vis atnaujinti įrašais duomenų bazėje

* `MainFragment`e `onResume` metode iškviesti `dbHelper.getScannedItemDao().queryForAll();`
* Sąrašo atvaizdavimui sukurti naują adapterį
* Sąrašo eilutės vaizdavimui sukurti layout'ą (pradžiai tik su `TextView` barkodo atvaizdavimui)
