Proposal: Switch to relative imports

[plhrtr]

Right now, every file is mapped via the jsconfig.json and the import map in editor.hmtl, so for each new file a new entry is needed.

• Leads to bigger files, to save entries
• Leads to merge conflicts as these files tend to be shared across branches

But relative imports on the other hand can get pretty big and ugly -> define a view base paths, like @sidebar/, @editor/ etc and use relative imports from there (our Js code is propably not structured enough for this)
