Renamed IdealWirelessMac to IdealMac.

Renamed all affacted classes and models.
The implementation didn't contain any wireless specific code.
Various IdealMac changes.

Adapted to the new radio interface using signals.
Various IdealRadio changes.

Renamed IdealAirFrame to IdealRadioFrame.
Renamed IdealChannelModel to IdealRadioChannel.
Simplified the implementation.
Various SimplifiedRadio changes.

Adapted to the new radio interface.
Renamed Radio to SimplifiedRadion.
Renamed ChannelControl to SimplifiedRadioChannel.
Renamed propagation directory to attenuation.
Also renamed a number of other classes and models according to the new naming scheme.
Various Ieee80211Mac changes.

Adapted to the new radio interface.
Added signal listeners and controlling the radio mode.
Renamed channelControl submodules to radioChannel.
Fixed oppfeatures to reflect recent changes.
Migrated the BMac mac layer from MiXiM to INET.

Adapted the implementation to signals and the interface of the new radio model.
Migrated the Flood network layer from MiXiM to INET.

Adapted the implementation to the interface of the network layer.
Migrated some MiXiM utils to INET.
Migrated some MiXiM base classes to INET.
Migrated the MiXiM radio into INET.

The new radio model is called the detailed radio model, because it provides a more detailed
radio signal model (e.g. in terms transmission power over time and frequency, etc.).
Adapted the model to signals and the new radio interface.
Migrated MiXiM battery modules into INET.

TODO: merging and cleaning up the two battery interfaces
Changed Ieee802Ctrl to implemented ILinkLayerControlInfo.

This change allows more generic handling of link layer control infos.
Added a new generic WirelessNic that contains a single mac and radio module.
Added a new example that demonstrates different NIC configurations.

Contains 9 configurations for all combinations of
 - ideal, simplified and detailed radio models
 - ideal, BMAC, IEEE 802.11 mac models
Deleted some obsolete (due to moves and new radio interface) files.
Fixed bug in AddressResolver during resolving interface ModuleIdAddress and ModulePathAddress.
Fixed bug in configuring router id in IPv4RoutingTable.
Removed obsolete NotificationBoard notification types.
