Add: added a function to get an arbitrary role of a model item

Browse Source 
Example:
$D{appdata.Column_1}
$S{
var vRow = line('DataBand1') - 1;
// 8 - Qt::BackgroundRole
var vColor = getFieldByRowIndexEx('appdata.Column_1', vRow, 8);

THIS.backgroundColor = LimeReport.color('lightgray');
if(vColor > '')
{
	THIS.backgroundColor = vColor;
}
''
}

Added several functions to get extended information from the model

- getFieldByRowIndexEx2(fieldName, rowIndex, roleName), default:
Qt::DisplayRole

- getHeaderData(fieldName, roleName), default: Qt::DisplayRole

- getHeaderColumnNameByIndex(datasourceName, columnIndex), default:
Qt::UserRole or Qt::DisplayRole

- getColumnCount(datasourceName), default: -1
