v1.12.11

-- Fix some small bugs and inconveniences adding function calls to proc stream in ProcStreamEditGUI.
     a) Allow multiple entries in proc stream of the same function and even same usage. Going through the motion artifact exercise in the
        fnirs course requires being able to do this that this should be legal. Therefore it should be legal.
     b) When adding function the focus in the proc stream listbox should be on the newly added entry.
     c) The gap separating the colon (the one separating function name from usage) from the function name in proc stream listbox kept getting bigger adding more and
        more functions. Fixed it by getting rid of all gaps when re-tabularizing so it's forced to a known state.
