Portable version, proxy and native TOR support

[TorContributor]

Matrix was created as a decentralized and anonymous protocol, and Element, as the main web client for Matrix, should support the original idea.

Element desktop and android applications in its current form are seriously lacking several functions to ensure acceptable level of anonymity for users without third-party programs.

1. We don't have official portable version for desktops. Unofficial builds are not only outdated, but most importantly, they are untrusted and cannot be verified as non-honeypot by majority of users. Portable version is really important to install & work with it in secure environment, like hidden VeraCrypt container.

2. Users can't add proxy for Element in settings so that Element application shouldn't work without selected proxy (for example, most Telegram clients have this functionality). Users have to use third-party VPNs/proxy, which, if they don't work correctly (or if the user forgets to turn them on), will lead to a leak of the user's real IP address. This is a crucial problem for both clients, desktop and mobile.

3. I recommend to add native TOR proxy support, if possible. I don't know, is it hard on the technical side or not, if not so hard - it will be really good. If this is difficult task, users can just add Tor proxy in application if previous enhancement about proxies would be implemented (but it won't work on mobile).

I'm surprised that after decades of Element development, none of this has been added. Are there any good reasons why this is not the case? I'm really looking forward to hearing from the developers.

Sincerely, Tor Enjoyer.
