- fix aot not being debug-able locally in jitsi-meet-electron app

The majority of the code is in the WASM file, the JS is just 9KB.
It's so little, in fact, that the performance hint for the main bundle didn't
have to be adjusted.

Allow path separator of \ in addition to / in jQuery's path name.

We are off my 1KB oh well.

app.bundle.js before: 3851549 after: 4506493.

The culprit for the bloat was Olm. It feature-detects the environment in order
to pick a suitable random byte generator, and alas Webpack includes the None
crypto pollyfill. This is due to the existence of the "node" block in our
Webpack configuration file.

The solution is to provide empty modules to make bundling work, as we did
already for the fs module, since we know they are not used at runtime.

Adapt to E2EE changes in lib-jitsi-meet. Notably:

---
    e2ee: introduce per-participant randomly generated keys

    This the second stage in our E2EE journey.

    Instead of using a single pre-shared passphrase for deriving the key used for
    E2EE, we now establish a secure E2EE communication channel amongst peers.

    This channel is implemented using libolm, using XMPP groupchat or JVB channels
    as the transport.

    Once the secure E2EE channel has been established each participant will generate
    a random 32 byte key and exchange it over this channel.

    Keys are rotated (well, just re-created at the moment) when a participant joins
    or leaves.

Up until now we relied on implicit loading of middlewares and reducers, through
having imports in each feature's index.js.

This leads to many complex import cycles which result in (sometimes) hard to fix
bugs in addition to (often) breaking mobile because a web-only feature gets
imported on mobile too, thanks to the implicit loading.

This PR changes that to make the process explicit. Both middlewares and reducers
are imported in a single place, the app entrypoint. They have been divided into
3 categories: any, web and native, which represent each of the platforms
  respectively.

Ideally no feature should have an index.js exporting actions, action types and
components, but that's a larger ordeal, so this is just the first step in
getting there. In order to both set example and avoid large cycles the app
feature has been refactored to not have an idex.js itself.

* Lang folder removed from proxy server and now using from local dev dir

* Added Marathi 100% langulage transalation

Without changing the 'Host' header, a standalone instance we use for
jitsi dev work will generate:

config.websocket = 'wss://localhost:8080/xmpp-websocket'

This was fine with BOSH, but a Websocket will not connect.

With this change it will be(based on the default devServerProxyTarget):

config.websocket = 'wss://alpha.jitsi.net/xmpp-websocket'

The currently selected values are a bit above the actual sizes, so if a PR
increases the bundle size enough to trigger the failure, it should bump it.
It better have a good reason for it though!

Build as follows to build (production) bundle size stats:

npx webpack -p --progress --analyze-bundle

Then open the report:

npx webpack-bundle-analyzer build/stats.json build/

They are in Stage 3 and are already dependencies or the React Native preset.
