Add Bitmask enum to get a clear code on NetworkConnectionSetting

The ideia is create a Bitmask (enum type) to make the NetworkConnectionParameter clear.

Examples:

public enum Bitmask {

AIRPLANE_MODE (1), ALL_NETWORK_ON(6), DATA_ONLY(4), WIFI_ONLY(2), NONE(0);

private int bitmask;

private Bitmask(int bitmask) {
	this.bitmask = bitmask;
}

public int getValue() {
	return bitmask;
}

}

Sample code…

This…
NetworkConnectionSetting ncs = new NetworkConnectionSetting(Bitmask.AIRPLANE_MODE.getValue());

Insted of this
NetworkConnectionSetting ncsModoAviao = new NetworkConnectionSetting(true, false, false);

Or even the original int bitmask (table locate on this link)
NetworkConnectionSetting ncsModoAviao = new NetworkConnectionSetting(6);
