serve_forever() and SIGTERM / SIGINT handling

[GoogleCodeExporter]

As of version 0.7.0 pyftpdlib automatically 'handles' SIGTERM (SystemExit) and 
SIGINT (KeyboardInterrupt) signals and executes a cleanup before exiting.
Also, it logs when the server starts and stops.

This behavior is generally desirable but there should be the possibility to 
turn it off so that the user can decide what to do instead (e.g. log another 
message or DO NOT catch the exceptions in the first place or register a signal 
handler).

As such I introduced (r1144) a new 'handle_exit' parameter for 
FTPServer.server_forever() defaulting to True.
The user will tipically do something like this:

try:
    server.server_forever(handle_exit=False)
except (SystemExit, KeyboardInterrupt):
    ...

...or register a signal handler.
