* Removed option to attach KeePassXC to the browser extension. Users must use the proxy application to communicate with KeePassXC. * Significantly streamlined proxy code. Used same implementation of stdin/stdout interface across all platforms. * Moved browser service entry point to BrowserService class instead of NativeMessagingHost. BrowserService now coordinates the communication to/from clients. * Moved settings page definition out of MainWindow * Decoupled BrowserService from DatabaseTabWidget * Reduced complexity of various functions and cleaned the ABI (public vs private). * Eliminated BrowserClients class, moved functionality into the BrowserService * Renamed HostInstaller to NativeMessageInstaller and renamed NativeMessageHost to BrowserHost. * Recognize XDG_CONFIG_HOME when installing native message file on Linux. Fix #4121 and fix #4123.
