[implemented] Treat prefixes to "%S" the same way as postfixes

[petermad]

If I in a button parameter use %Sx the x is appended to the end of the LAST file selected name.
If I use "%Sx" then x is appended to ALL selected file name - that is a nice feature.

But if I use "x%S" then x is only added in the front of the FIRST selected file name - it would be nice if x was added to ALL file names like for "%Sx"

29.04.24 Added: Button bar, start menu, parameters field: Better handling of parameters %S, %R, %P%S and %T%R in double quotes with prefix text: "beforename%Sbeforeext%Eafterext" inserts string 'beforename' before the name, 'beforeext' before the last dot and extension, and 'afterext' after. (32/64)

Thanks for implementing beforename%S - i works just fine
