NNetSimu 2.1

Version 2.1 brings following some new features, bug fixes and improvements:
 * New feature Rotate model
 * New feature Rotate selection
 * Bug fix: Crash when stopping "Find loops" with the ESC-key
 * Bug fix: Crash when defining trigger sound for output neuron
 * Improvement: Selection rectangle with better precision. Before, the selection sometimes included nobs (especially pipes) not really inside the rectangle. Now a pipe is included in the selection if and only if both endpoints are inside the rectangle.
 * Improvement: When defining a selection with the right mouse button, any previously existing selection is automatically removed.
 * New feature: The command copy selection can also be triggered with the keyboard shortcut Ctrl-C (Strg-C).
 * Simplification: "Closed connectors" and all related commands are no longer needed. In the former version, when combining an input neuron and an output neuron by using the plug connector command, a closed connector resulted. This was a coupled set of neurons, similar to input connectors or output connectors. But there was no real usage for this type of connector. In all realistic scenarios, the closed connector was immediately transformed into a set of independent neurons by using the Disconnect command. Now this indermediate step is no longer neccessary. The plug connector command produces directly a set of independent neurons. For the user, the process of connecting modules is simplified. Some commands are saved, which makes menues shorter. The program code is simplified and some rare logic problems which could cause errors are no longer existing.

The EEG subsystem has been reworked
 * Bug fix: Saved EEG signals didn't show up in EEG monitor window
 * New feature: Create/delete/move/size EEG sensor commands can now be undone/redone
 * New feature: The delete EEG sensor command is now also available in the context menue of EEG sensors in the main window. Before you had to go to the EEG monitor window to remove a sensor/signal.
 * Improvement: Correlation of EEG sensor in the main window and related EEG signal in the EEG monitor window is now visualized better. If mouse cursor is over sensor or over signal, the sensor and the signal are both highlighted.
