Fixes and tuneup

* Reduce duplicate methods perform same task into one simple function.
* Use EmuShared to obtain updated log settings instead of WM_COPYDATA message.
* FIXED: Set log config for second GUI process
* FIXED: Proper update logging config to EmuShared instead of repeatly send when it is indeed in use.
  * Without this fix, it will affect other GUI process emulating a title.
