Revert patch to non-crashing mp version while hunting for solution

Hot fix:
- Add/fix collapsible section headers
- Fix text in MP campaign intro popup

temporarily disabled the killswitch

HUGE YEARS-LONG UPDATE:
- the unreadable black text in the front menu is now readable white text.

Pressed the magic button that makes you all stop saying "update please"

ULTRA HOT FIX
- shit won't get absolutely right fucked due to having non-latin characters in your Windows username or file paths
- the lil outdated flag will also go away, more importantly

Coldfix/Update
- Add a new option type: an Action Button. Actions are just text buttons that can do stuff when pressed. Use `mct_mod:add_new_action(option_key, button_text, callback)` to create a new action button, where callback is a function that is triggered whenever the action button is pressed. No support for locking or unlocking the action button yet, or really anything but setting the text and the callback that's triggered when the button is pressed. That'll come next patch!
- Add a lock icon to any locked options; the lock-reason tooltip is now attached to the icon.
- Add scroll-bar to the "description" tab of any MCT Mod
- Add numerical version support for MCT and MCT Mods.
-- Tweaked function:`mct_mod:set_version(version_num, version_name)`. Should be backwards compatible - a missing "version_name" will be created from the version_num, and a missing version_num is set to 0. Scream at me if this gets goofy.
-- New function: `mct_mod:get_version_number()` -> version num.
-- Set MCT version number to 0.9, and the version name remains 0.9-beta
-- Number will only be used for backend considerations, per Ulrik and paperpancake's request. Let me know if this doesn't float your boat.
- Fix the auto-saves; the game should only be forcibly-saved if the game has already been saved AND if there have been edits to any MCT settings. Will continue to look into the best way around this issue
- Fix the game logging option so it will now properly unlock when you disable script logging from another mod
- Fix dropdowns and sliders not displaying their lock reasons
- Fix Dummy options and Action options having unnecessary icons

- disable debugging shit again
- MCT will now regenerate broken settings files (which were caused two-three patches ago, whatever kicked off this whole thing)

- fix the previous bug fix

- Remove some testing shit I forgot to disable (:
