This adds a `file-loader` rule to the Webpack build so that any requests for
image resource will be output into the app's output directory, but with an extra
content has appended so that we can safely use a long cache lifetime.
The CSS and SCSS rules are also changed to use `css-loader` so that any `url`
inside is automatically processed by the new image rule above.
needs server to support 1600x1200 thumbnails for retina large ones.
ideally need to cap maximum thumbnail size to 800x600 rather than expand to arbitrary widths.
need to check that luke's funky timeline code doesn't get confused between naturalWidth and infoWidth etc.
also need to consider whether to encode a resolution metric in the event rather than lying about resolution.
App checks at startup for an existing session, if there isn't one,
it will start the tool to check for a login in the file:// origin.
If there is one, it will copy the login over to the vector://vector
origin.
In principle this could also be used to migrate logins between
other origins on the web if this were ever required.
This includes a minified copy of the browserified js-sdk with
a getAllEndToEndSessions() function added to the crypto store
(https://github.com/matrix-org/matrix-js-sdk/pull/812). This is
not great, but for a short-lived tool this seems better than
introducing more entry points into webpack only used for the
electron app.
Hopefully makes the syntax a bit nicer. Also uses ES6 async import
rather than require.ensure which is now deprecated. Also also
displays an error if the component fails to load rather than falling
over in a heap, which is nice.
