Submit point: use names and titles, not identifiers

[hugoroy]

In https://tosdr.org/submit-point.html (src/js/pending-point.js) right now the user can select a service and a topic, but the interface displays the identifiers. Identifiers are machine friendly, and they don't change. But they are not nice for users.

TODO

The interface should

• display the services' name instead of the id (see https://github.com/tosdr/tosdr.org/wiki/Specification:-services)
• display the topics' title (see https://github.com/tosdr/tosdr.org/wiki/Specification:-topics)
