GUI freezes for some time

[jacobly0]

Checking "Pause emulation on focus change" and then leaving CEmu unfocused for a long time causes the GUI to freeze for an extended period of time when CEmu is focused again. This is caused because the status update continues firing at Update status frequency while emulation is paused causing an absurd number of connections to be created, which takes a long time to sort out when number of seconds CEmu was unfocused signals have to be processed at 60Hz until all of the connections eventually get disconnected. Reported by Runer and diagnosed by me.

You can make this trigger much faster by changing

CEmu/gui/qt/settings.cpp

Line 692 in 71a4da8

m_timerEmu.start(value * 1000);

to a really low value before 8afafaf.
