* Serve translation files from the karma server
* Port UserSettingsStore to ES6 exports because the test runner
gets confused by ES6 importing a commonjs module
* Remove extra spaces in translations strings for MELS
* Fix 'his/her' back to be 'their'
* Change test to expect singular 'invitation' for a single person
(there may be multiple invitations, but IMO this should be
'rejected n invitations' and we can play with the wording later,
I don't think the singular is any worse than the plural).
* set language in the MELS tests (and wait for it to complete)
* Don't bother setting lang in other tests for now
- Instead of using one attribute, use one that might just contain one token
- Use the first token when tracking a child
- Mandate that no commas can be in individual tokens
This adds the `data-contained-scroll-tokens` API to elements in `ScrollPanel` which allows arbitrary containers of elements with scroll tokens to declare their contained scroll tokens. When jumping to a scroll token inside a container, the `ScrollPanel` will act as if it is scrolling to the container itself, not the child.
MELS has been modified such that it exposes the scroll tokens of all events that exist within it.This means "Jump to unread message" will work if the unread event is within a MELS (which is any member event, because even individual member events surrounded by other events are put inside a MELS).
To fix https://github.com/vector-im/riot-web/issues/2916, force the checking of scroll position by calling _onWidgetLoad (might need renaming...) when a MELS is expanded/contracted.
Also use an keying scheme for MELS that doesn't depend on the events contained, but rather a simple incrementing index based on the order of the MELS as it appears amongst all MELS.
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 ...
