Pause on lost focus inconsistent spelling.

The pause on last focus option (F3+P) is spelled inconsistent among feedback.

debug.pause_focus.help=F3 + P = Pause on lost focus
debug.pause_focus.on=PauseOnLostFocus: enabled
debug.pause_focus.off=PauseOnLostFocus: disabled

(Lines 3075, 3088 and 3089)

These are the from en_us.lang and as you see, once it's called "Pause on lost focus" and the other times "PauseOnLostFocus"

Fixed translation strings:

debug.pause_focus.help=F3 + P = Pause on lost focus
debug.pause_focus.on=Pause on lost focus: enabled
debug.pause_focus.off=Pause on lost focus: disabled
