add a config handler class + make cross platform

[sillychipmunk]

~needs to be tested, this is developed on a mac which doesn't support win api and I cant get Tk working~ <- fixed it, installed python from official site

• [x] Test on macOS (~albeit very limited to how easy it is to use.. and need to find a way to get mouse location~)
• [x] Test on Windows (should "just" work)
• [ ] Test on Linux (~need to find a way to get mouse location~) (can be skipped, dont want to bring up a linux just to test)

It seemed pyautogui had a mouse location function that is cross platform

fixes #18 fixes #47 (by the fact that an empty string split by comma will yield an empty array which does nothing) fixes #45 (not for the belt coords though)

@x-actly for the issue of disabling default hardener logic, I have removed the default "F3". We can discuss if we want it as default, but I think given the name of the repo and its intention to be used mainly in highsec the importance of drones cannot be underestimated. To activate a set of combos to execute when leaving station now, you set them as a comma separated string in hardener_keys in [SETTINGS] like this

[SETTINGS]
hardener_keys = F3, Alt-F2, Alt-F1

I decided to show an estimation of time to complete that changes when you update runs, hold or yield. Should maybe show it as decreasing reset timer like before But it was not trivial 😅

I had a zero division issue when I tested the pull request, but you had fixed it in the meantime. All good :D
