Allow double values for count fields

[johnjohndoe]

The importer allows to import Measured values of type Count as shown in the screenshot.

The values for this column are processed here:

// COUNT
else if (m.getValue().equals("COUNT")) {
    return Integer.parseInt(value);
}

Integer values are expected here.

Error case

If the values is provided as a double value such as 23.0 the following error occurs:

[org.n52.sos.importer.feeder.task.OneTimeFeeder] ERROR SensorObservationService - 
    Could not retrieve all information required for insert observation because of 
    parsing error: java.lang.NumberFormatException: For input string: "23.0". 
    Skipped this one.

Feature request

Please consider processing double values such as 23.0 as 23 or 0.0 as 0 instead of skipping the value.
