0.9.13 - Public Release

First public announcement release.

0.9.13 - Tray "Open" Fix

• Tray "Open" required two clicks when "Start minimized" was enabled: the GUI process spawned by the tray honoured the start_minimized setting and started hidden, so the first click launched an invisible window and only the second click (routed via IPC show_window to the now-connected client) presented it — the daemon now spawns the GUI with a new --show flag that overrides start_minimized on first activation, so an explicit tray click always shows the window immediately; start_minimized still applies to plain mtsync launches such as login autostart
• Daemon/GUI mutual spawning prefers /proc/self/exe over PATH lookup: both the daemon launching a GUI and the GUI launching a daemon previously resolved mtsync via Glib::find_program_in_path first, so a development build would silently launch a stale system-installed binary; the running executable's own path is now preferred, with PATH lookup as fallback
