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.
