This PR is related to this issue: #676

What's new

• ✨ Add an onboarding screen (only appear on first launch)
• 🇫🇷 French translations for the new onboarding screen
• 🛠 Reorganize AppDelegate a bit
• 🛠 Move View Controllers into folders

Tests

I've tested the onboarding screen on both small and large screen, HiDPI and normal res, light and dark mode.

If you want to test the PR you can save your preferences located here:

~/Library/Preferences/me.guillaumeb.MonitorControl.plist

and run this command to reset your current preferences (where the app check to know if it was started once)

$ defaults delete me.guillaumeb.MonitorControl

before the launching the project in XCode.

What's left to do

All current translations beside French & English (for the new onboarding) are missing for now.
