Gonna refactor setsave(), it doesn't need to modify global instance

[tactu1]

Part of refactoring to separate UI code from logic, first road block is the set save function.
I'm going to have it returning the lists that it needs (currently)
global VarSmodules
global DoubleModules
global VarPistols

as a list of lists
and then you can set the output of the function to a variable and then assign them. This will let you declare those lists in a better spot and it will let us create a unit test for the function.
