Added mobilityStateChanged signal to the interface of mobility modules.
Moved generic queue modules into a separate directory.

They are not strictly related to link layer.
Fixed NED package names after moving modules.
Added the new radio interface to the physical layer contract.
Deleted some obsolete (due to moves and new radio interface) files.
Moved the current radio implementation into a separate directory.

There will be 3 different kind of radios: ideal, simplified and detailed.
Moved the ideal radio into a separate directory.
Moved the old link layer contract into the common directory.

This isn't really a contract in the sense of being the common interface among different link layer implementations.
Added new link layer interface to the contract directory.
Moved the IPv4 contract into a separate directory.

This is rather a contract among different IPv4 implementations.
Moved the IPv6 contract into a separate directory.

This is rather a contract among different IPv6 implementations.
Added a new physical layer contract.

It is rather a placeholder now than an immediately useful interface.
Various ideal radio changes.

Renamed IdealAirFrame to IdealRadioFrame.
Renamed IdealChannelModel to IdealRadioChannel.
Simplified the implementation.
Various simplified radio 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.
Renamed ideal wireless to ideal mac.

Renamed all affacted classes and models.
The implementation didn't contain any wireless specific code.
Added the new network layer contract.
Various ideal mac changes.

Adapted to the new radio interface using signals.
Various IEEE 802.11 mac changes.

Adapted to the new radio interface.
Added signal listeners and controlling the radio mode.
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.
