Request modification of various set_xxx() functions

[smith92clone]

There are several set_xxx() functions for FoldIt parameters.

None of these functions return any values.

It would be useful if the set_xxx() functions would return the previous value of the parameter being set.

Example: Current code

local save_param = get_xxx()
set_param(new_value)
  ... do something ...
set_param(save_param)

Return the previous value results in

local save_param = set_param(new_value)
  ... do something ...
set_param(save_param)

Sounds useful.

And to just get a parameter, you can use the set function with no parameter, right?
