Improve loading of typings when the adapter is disabled

[AlCalzone]

When the adapter is not running, the editor cannot load the typings and thus can't do syntax and type checking.

This can be improved by...

• [ ] storing the NodeJS (@types/node) and ioBroker (javascript.d.ts) typings in an object like the scripts
• [ ] assembling the global script typings in the frontend

@AlCalzone Done?

[AlCalzone]

No I didn't do anything on the typings / TS stuff while you were reworking the editor for 4.0. I can take another look when I find the time to.
