Revert "Remove autosave.js from view..."

This reverts commit 5b6644cb89e51a9faf053f5c8d69d92b2c1952fe.
Fixes autosave.

We currently trigger the autosave after the user stops writing for 1 second. Maybe it would be more convenient to trigger it every N second instead.

Solves issue #297.
Advances issue #322.
Merge branch 'milestone/publify-8' into bug/fix-autosave/297
