Few bottom-bar fixes

* Added margins, now it should look nicer when there is not enough space for everything
* Cursor-position div should be now where it belongs
* Added one more divider, on the right (with DIRTY FIX, should be changed next)
Sidebar fixes

Now editor should be resized properly and scrollbars should be shown/hidden properly.
Cleanup

No more dirty fix.
