Upon request the set of Menu Buttons has been extended to

/Experiment/Menu Buttons = Start, Pause, ODB, Messages, ELog, Alarms, Programs, 
History, Config, Help

by adding the additional "Pause" string. Without "Pause" being present in the list of 
menu buttons, the run cannot be paused/resumed, but only started/stopped. This is 
required by some experiments. If "/Experiment/Menu Buttons" is not present in the ODB, 
it gets created with the above default. If it is there from the previous update, the 
"Pause" string might be missing, so it must be added by hand if required. The 
modification is committed as revision #4684.
