@aurum/record: Forbid launching two records at the same time in one vim instance
Make AuRecord use aurum://edit to edit buffers, thus not touching
possibly already opened ones. Fixes #16 (no need to unmap
anymore), fixes #15 (no need to reload as well)
The above also fixes ref #14, but only if buffer opened on the
right (likely aurum://file) also got bufhidden=wipe
