Reorganize tweaks

[Disassembler0]

Since the conception of the script, the tweaks were divided into 4 main categories (privacy, services, UI and applications). Later, security was split from privacy and services, and Explorer UI tweaks were split from the rest of UI. Nowadays, we have much more tweaks than in the beginning and this categorization is not sufficient anymore.

Once the tweaks are grouped (#241), there will be less of them, but there still may be need to redo the structure to make the navigation and relations between the tweaks clear. E.g. to split Libraries icons on Desktop and in This PC from the Explorer UI tweaks, split Defender tweaks from the rest of security, put networking to a separate group etc.

In my opinion it would also make sense to reorganize or add extra label for tweaks that only apply to this current user's profile or the local machine. For instance, the setting in "HideQuickAccess" can be used in HKCU as well, not just HKLM. For people who like to tweak their user profile only - even if it's due to lack of admin rights or the current user is no admin account - this would be super handy. What would you suggest for new names? Something like "HideQuickAccess_CU"? Would be good to know, as I noticed it would violate the 25 characters rule in some cases. Personally I think it would be definitely beneficial to raise it to something like 30 characters.
