Change Event Handling methods, other fixes

Run lglw_events in effEditIdle (debug plugin)
Run lglw_events in effEditIdle (VSR plugin)
Run effEditIdle loop in debug host if no _XEventProc
Temporarily swap lglw_log for printf (needs fixing)
Suppress most mouse event messages
Bring back sending of child events to parent (rare occurence)
Cleanup some lglw_window_open code
lglw_window_open event mask setup to receive events for itself
Comment the setting of _XEventProc (to get to effEditIdle loop)
NoEventMask on mouse grabbing, possible fix for grabbing issues
Setup working and non-blocking lglw_events

Fix mouse buttons, glXSwapIntervalEXT call, and bubble-up unused events

Implement many `lglw_*` functions and X Events for Linux

Special keys affect modifiers and send specific LGLW codes
Other keys send the X KeySym for the key
Remove unused key hooks
Add queued mouse warps to redraws

FocusIn/FocusOut simply to see them in the log
EnterNotify/LeaveNotify are basically complete
MotionNotify is basically complete
ButtonPress/ButtonRelease are basically complete

lglw_mouse_grab is implemented but unable to test currently
lglw_mouse_ungrab is basically complete
lglw_mouse_warp is implemented but unable to test currently
lglw_mouse_cursor_show is basically complete, perhaps could have the cursor refactored to the struct
