Prevent blind overwrite of user's configuration

Browse source 
Just as it happens for the `/etc/network/interfaces` it would be more polite to actually ask the user if they want to overwride their `/etc/NetworkManager/NetworkManager.conf`.
Changing this file by force will most likely shut a user out of their PI, because of wifi MAC address randomization, which is hardly the expected behavior from an install script.
__Those choosing to use this install script do it to keep control over their machine, which includes avoiding unexpected deletion of their config files.__

For instance, things work just fine for me with the following `NetworkManager.sh`:
```
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no
```

If something out of the downloaded `NetworkManager.sh` is actually mandatory (doesn't seem so tho) It's would be better di explicitly explain it to the user so their can take actions, rather than causing them unexpected behaviors.
