Convert flex to do lists into issues

[Croydon]

Issues should be the only place for planning, therefore please convert the to do lists from flex into issues please and remove them.

[Croydon]

The following needs to be revisited and converted potentially in issues:

---

The REST API
The REST API (v1) is wired together in server/api/v1/index.js
Documentation via swagger should follow soon enough.

---

and

---

Future features
This is either to-do or nice to have

• add example modules and user documentation a-la readthedocs
• test everything extensively, fix passages that are marked with TODO (and add unit tests!)
• authentication via OAuth
• more secure server
• sandbox-based plugin system
• server lister and package lister

---

I'm going now to remove it from the readme.
