Pass cursor move event to the script

Set initial window scale to 0 because wayland freezes the process when it's not >0.
Provide more information from `llua_mouse_hook` about why the callback is failing.
Prevent call to `llua_init` when provided lua_load script doesn't exist.
- This caused me a headache and now lua_L won't be initialized if the
  script doesn't exist. This prevents a missing file from causing later
  issues which might be harder to catch.
Feature gated X11 in mouse-events.h/.cc files.
