Create an abstraction to control JSONs better

[Worie]

There's a mess in Utilities or Events.ts files - because jsons need some manipulations to work properly in BetterTouchTool. I'd like to create a separate service for managing this part of the package

I'm still considering if it's worth an effort, as management of actions is much easier than it used to be at the time of creating this issue

Closing for now.
