Merge pull request # 400 from matrix-org/daniel/versioning

Rename presence_handler.send_invite

Copy rather than move the fields to shuffle between a v1 and a v2 event.

Rename presence_handler.send_invite to presence_handler.send_presence_invite to distinguish it from normal invites

Allow paginating search ordered by recents

Run sytest against postgresql

Return words to highlight in search results

This should make all v1 APIs compatible with v2 clients. While still
allowing v1 clients to access the fields.

This makes the documentation easier since we can just document the v2
format and explain that some of the fields, in some of the APIs are
duplicated for backwards compatibility, rather than having to document
two separate event formats.

Allow user to redact with an equal power

Users only need their power level to be equal to the redact level for
them to be allowed to redact events.

Postgres doesn't support them like this.

We don't have a bool type in common between postgres and sqlite.
