#ttp 331470 - UnrealVS: toolbar combos disabled
#branch UE4
#proj UnrealVS
#summary
#change Minor refactor of BatchBuilder class to avoid issues when starting UnrealVS and loading options before the batch builder window opens.
#change Improved tick thread startup and shutdown. It only runs when a solution is open. This allows it to shutdown cleaner when VS closes.
#change Allowed the batch builder busy state to block solution closing. This should be prevented by VS anyway as a build would be running.
#change Minor refactor of the way CommandLineEditor and the StartupProjectSelector enable/disable and update their combo controls.
#change Version to 1.30
