Generate human readable IDs for client URLs (#77)

Browse Source 
Based on @FranzSkuffka's suggested enhancement in PR 207 on
localtunnel/localtunnel
(https://github.com/localtunnel/localtunnel/pull/207), this PR uses the
"human-readable-ids" package to generate IDs of the form
"adjective-noun-number". These IDs are easier to remember and arguably
more useful in testing since they can be retyped without copying and
pasting.

Some sample IDs generated by this package are:

* heavy-puma-90
* grump-walrus-64
* purple-starfish-58
* nasty-seahorse-9

lt --host http://sub.example.tld:1234 --port 9000
```
You will be assigned a URL similar to `qdci.sub.example.com:1234`.
You will be assigned a URL similar to `heavy-puma-9.sub.example.com:1234`.
If your server is acting as a reverse proxy (i.e. nginx) and is able to listen on port 80, then you do not need the `:1234` part of the hostname for the `lt` client.
