sus URL shortener


## `susmng` usage (managing shortlinks)

- creating a new shortlink at https://pls.cx/shortlink

        susmng [-s pls.cx] create -l shortlink -v https://example.com

- deleting the shortlink https://pls.cx/shortlink

        susmng [-s pls.cx] delete -l shortlink -v confirm

- listing all shortlinks on the server pls.cx

        susmng [-s pls.cx] list

`susmng` will assume the first server in the `secrets` section of the configuration file if the `-s`
flag is not provided.
