Subject: [PATCH] Fix mouse cursor staying trapped in window on alt-tab

When the inventory or other UI with a hidden cursor was open,
alt-tabbing out would leave the cursor locked to the game window.
SetWindowFocused(false) from WM_KILLFOCUS correctly released the
clip and showed the cursor, but Tick() was unconditionally calling
SetCursorPos every frame to re-center it, overriding the release.

Added m_windowFocused to the Tick() condition so cursor manipulation
only happens while the window actually has focus.
