fixed documentation of Django requirements for 3.0.x
Standardised on "apphook" throughout docs

Existing examples included: AppHook, App-Hook, Apphook, apphook, app-hook

"Apphook" has been chosen for pragmatic reasons (for example, it reflects naming in the code
itself), and we must simply live with the stain of its ugliness on our consciences until we have
expunged it through penance and good deeds.

Also added a note on the future use of spaces rather than tabs in frontend ccode.

Documentation on the code & project management process

Describes a workflow for tickets - issues and pull requests - on
GitHub. This workflow uses a system of labels that help provide
key at-a-glance information about the state of any ticket.

In particular, the system is intended to provide unambiguous
information about a ticket's:

* status: a ticket's health and what stage the ticket is at in
the workflow
* needs: what next actions are required to move it forward

The existing labels on GitHub have been renamed and regrouped to
conform to this system.
