New Windows service parameters (disp-name, description) and some fixes

-p [--disp-name] title
Specify service display name. This is displayed in the list of services, while --name is used in "net start"-like commands. (-d letter was avoided as it is used for --daemon option in the server command line)

-c [--description] desc
Specify custom service description.

Fixes:
* Display usage when no action is to be taken.
* Display usage at most once.
* A typo.
