HickelSOFT RustDesk Custom Client

Based on the latest version of RustDesk.

Standalone Server - Only for use for HickelSOFT Huth GmbH customers! (Secrets: RENDEZVOUS_SERVER, API_SERVER, and RS_PUB_KEY)

Changes:

• Converted submodule libs/hbb_common into the main codebase.
• Builds only for Win32 and Win64, and additionally output Win32 and Win64 ZIP files (Changed file: .github/workflows/flutter-build.yml)
• Added HickelSOFT logo (Changed files: .gitignore, flutter/assets/logo_dark.png, flutter/assets/logo_light.png)
• Applied patch that allows dark/light logos to be displayed (Changed files: flutter/lib/common.dart)
• Removed "sad smiley" for empty peers list, since it confuses customers (Changed file: flutter/lib/common/widgets/peers_view.dart)
• Replaced update service with our own (Changed files: flutter/lib/desktop/pages/desktop_home_page.dart, libs/hbb_common/src/lib.rs)
• Desktop setting page: Added note about customizations and custom server in the About page. (Changed file: flutter/lib/desktop/pages/desktop_setting_page.dart)
• Install page: Desktop icon and RustDesk Pritner is default false (reason: HickelSOFT has own Desktop icon) and install printer is also default false (reason: Rarely used) (Changed file: flutter/lib/desktop/pages/install_page.dart)
• Undo "reduce the convenience", otherwise we cannot have a custom client anymore; Connection data as part of the filename is ugly and insecure. (Changed file: libs/hbb_common/src/config.rs)
  • (Note that they seem to have forgotten to remove option_env!("RENDEZVOUS_SERVER") in using_public_server() at src/common.rs. Keep watching that they don't remove it, otherwise add it again.)
• Changed this README.md file (Changed file: README.md)
• Token is not transmitted to HBB anymore, since API and HBB are distinct for us, and the token should not be transmitted unencrypted. (Changed file: src/client.rs)
• Disabled secure_tcp, because our server does not support KeyExchange. (Changed file: src/common.rs)
• Change some German texts for HickelSOFT (Changed file: src/lang/de.rs)
