#4 add settings files

[auz_engineer]

Create at least two setup files, one human readable/editable and another for settings in binary form. The code to read and write the files needs to be created at the same time, and should be able to create blank defaults files if they are not found where expected.

[auz_engineer]

the point of having two files is:

• Binary file contains info like window layout/visibility, user can delete file if windows are off screen on reloading.
• Human readable file will contain details like volume levels that may be adjusted by the user.
