Replace `Editor::current` by a macro

This is necessary to workaround ownership issues across function calls.
The issue notably arised when implementing the registers into `Editor`
and I was getting annoyed again when implementing copy/pasting into
system clipboard.
The problem is addressed by using macro calls instead of function calls.
There is no notable side effect.
