Working timing "function"

Now it's time for lunch!
Fully working copy of INI file for Ivan (not pretty)

The INI file for Ivan now fully works; selecting parameters and setting
exposure times of CMOS works fine. Now we need to change the output and
some other things a bit...

- Switching from manually inputting values to selection from list
- Setting the output directory at the 'correct' time
- Giving nice output (i.e. clearing the command line)
