GameEx 18.55

Looking to remove any possible video or input lag GameEx will now lower its process prioirty to idle after launching an emulator.

Fixes to the sync refresh MAME display feature. I revisited all this and looked at GroovyMAME usage on an LCD. It will work with GroovyMAME but on a 5 year old mini PC I reverted to vanilla MAME in my new Chewlix build, I incestigated all this again and other than going with a Mister, your best bet in 2024 is to go for a G Sync monitor for MAME for no tearing and input lag on an flat panel.

In MAME attract mode the bezel will try to show the logo first if available rather than marquee. Looks mich nicer.
