pid file created by deluged in config is non-standard

[Calum]

Currently the pid file deluged.pid created by deluged in config contains the port number.

This can cause unexpected results if a user creates a pidfile with the same name in the same location, as other applications expect only the pid to be in this file. e.g. ​forum thread

Possible solutions are to rename it or have a separate file for the port.

If I remember correctly, the port in the file is used by deluge to differentiate instances.
