* Implement simple team-based registration
Config required goes in the `teams` top-level property in config.json. This consists of an array of team objects:
```json
{
"name": "University of Bath",
"emailSuffix": "bath.ac.uk"
}
```
These can be selected on registration and require a user to have a certain email address in order to register as part of a team. This is for vector-im/riot-web#2940. The next step would be sending users with emails matching the emailSuffix of a team to the correct welcome page as in vector-im/riot-web#2430.
We still need to parse "plaintext" messages through the markdown
renderer so that escappes are rendered properly.
Fixesvector-im/riot-web#2870.

Add Modal.createDialogAsync, which can be used to display asynchronously-loaded
React components. Also make EncryptedEventDialog use it as a handy
demonstration.
Transition pairs joined,left and left,joined are now transformed into single meta-transitions "joined_and_left" and "left_and_joined" respectively. These are described as "joined and left", "left and rejoined".
Treat consecutive sequences of transitions as repetitions, and handle any arbitrary repetitions of transitions:
...,joined,left,joined,left,joined,left,...
is canonicalised into
...,joined_and_left, joined_and_left, joined_and_left,...
which is truncated and described as
... , joined and left 3 times, ...
This also works if there are multiple consecutive sequences separated by other transitions:
..., banned, banned, banned, joined, unbanned, unbanned, unbanned,...
becomes
... was banned 3 times, joined, was unbanned 3 times ...
The MELS can now deal with arbitrary sequences of transitions per user, where a transition is a change in membership. A transition can be joined, left, invite_reject, invite_withdrawal, invited, banned, unbanned or kicked.
Repeated segments (modulo 1 and 2), such as joined,left,joined,left,joined will be handled and will be rendered as " ... and 10 others joined and left 2 times and then joined". The repeated segments are assumed to be at the beginning of the sequence. This could be improved to handle arbitrary repeated sequences.
Instead of dropping the style attribute on `<font>` tags entirely, sanitise aggressively and only keep `background-color` and `color` keys, and also sanitise the values to prevent `url(XXXXXX)` and `expression(XXXXXX)` type XSS attacks.
