Subject: [PATCH] Expose session signal sending to QML

As QTermWidget's `Session` class already offers support for sending signals to the contained process it makes sense to expose this functionality to it's QML version.

Otherwise one would have to resort to fiddling around with process ids and system calls or further external applications inside QML to send signals to processes launched using the widget.

Adding a `stopShellProgram`  method to `KSession` complementing `startShellProgram` was also considered but exposing `sendSignal` offers a more general interface.
