Script Generator: Perform type checking

As a user of the script generator I would like the GUI to be as user friendly as possible. Typing of each parameters will help with this. For example:
* For an integer/float the user should not be able to input a char
* For a boolean the user should be able to use a checkbox

The type information should be stored in the Python configuration file. This is complicated by the fact that there is a requirement for users to be able to put a value in a cell that means `no change`. This ticket is to pass the information from the config on whether the parameters is:
* Boolean
* String
* Integer
* Float
and modify the cells in the table accordingly.
