Add menu entries to control the VM

It would be cool if you could add menu entries to control the VM without opening a terminal. I was able to add this by editing the `windows.desktop` file:


To do this, add the following to the `[Desktop Entry]` section in the `windows.desktop`:

```
Actions=start-vm;shutdown-vm;reboot-vm;suspend-vm;resume-vm;stop-vm;reset-vm;
```

And add these new sections:

```
[Desktop Action start-vm]
Name=Start VM
Exec=virsh start RDPWindows

[Desktop Action shutdown-vm]
Name=Shut down VM
Exec=virsh shutdown RDPWindows

[Desktop Action reboot-vm]
Name=Reboot VM
Exec=virsh reboot RDPWindows

[Desktop Action suspend-vm]
Name=Suspend VM
Exec=virsh suspend RDPWindows

[Desktop Action resume-vm]
Name=Resume VM
Exec=virsh resume RDPWindows

[Desktop Action stop-vm]
Name=Force stop VM
Exec=virsh destroy RDPWindows

[Desktop Action reset-vm]
Name=Force restart VM
Exec=virsh reset RDPWindows
```
