Add a simple downloads page (Feature Request)

It would be nice to have a unified place to download SchildiChat.
Right now to download SchildiChat for desktop you need to complete these steps:

1. Select platform (Android, Desktop, etc)
2. Scroll down to the "Where can I get it" section
3. Go to the all downloads (GitHub releases)
4. Get the appropriate file (Note that this part can be really hard for non developers)
5. Done!

It's not a major issue but it has been very intimidating to people I've recommended SchildiChat to (Non-technical users).

Here is some of the things I think would be good:

• Direct to an appropriate download page for the target platform (based on user-agent or similar)
• Have a button to choose a different platform (In case the user-agent is incorrect)
• Have a direct download link to the correct file from the latest GitHub release.
