Decouple Org and Bog tree-to-indirect commands

- Use Bog-specific record of last indirect buffer instead of
  clobbering org-last-indirect-buffer.
- Add variable that controls whether or not previous buffer from
  bog-citekey-tree-to-indirect-buffer is replaced during the next call
  (default behavior).
- Show indirect buffer in other window regardless of
  org-indirect-buffer-display setting.
