[Ovmsdev] NetManTask created twice

[Michael Balzer]

I need to check if everything gets cleaned up in the webserver on "network.mgr.stop".

I currently rely on mongoose sending all connections an MG_EV_CLOSE on shutdown, and I haven't checked if that is that guaranteed to happen.

But that could only lead to a memory leak if the netman instance would be shut down while serving a file (ROM/SD) or command result.

Regards,
Michael
