Implement the technology configuration dialog

[Henrik Heimbuerger]

Add a third configuration dialog, used to detect, configure and initialize the settings of the connectors.

The following tabs are needed:

• 42: Allows to assign IDs to cars.
• BlueRider: Allows to choose COM port of the Bluetooth interface.
• Analogue: Allows to enter host that runs the network interface.

A button at the bottom allows to accelerate the cars (separately) for a few centimeters, to test whether the connection is working.

This includes creating a ConnectorManager (ConnectorConfigurationManager?) that stores a SlotCarSystemConnector for each connected car and that is used by the PlayerSettingsDialog to assign connector IDs to players.

Code can be derived from #39 when it's completed, as the LnF should be similar and all the layout manager crap doesn't have to be done twice. :)
