Use in-place navigation flags for `limit` and `start`

Previously, all flags needed to be at the start of the command,
right after `razor`. This would not be intuitive for adding
`limit` and `start` features, since `razor --limit 1 events`
makes less sense than `razor events --limit 1`.

Move `--full` and `--short` after collection

Previously, all query flags needed to be right after
`razor`, e.g. `razor --full events`. This moves
these query flags to their more natural position,
right after the collection navigation, i.e.
`razor events --full`.

RAZOR_API URL must start with http: or https:

Issues were arising from URLs that do not contain
the protocol at the start. This resulted in an
"opaque" message when trying to do navigation
and pass query parameters. URLs passed by -u
or --url will result in an error if they do not
start with the protocol.
