Title: Documentation fix for issue #236

Provide a section in the documentation that warns mptt users about the concurrency issues and about the fact that it's their responsibility for ensuring mutual exclusivity.

* this fixes issue #236
* also add a new link to an mptt tutorial (I find this more usefull than the existing ones as it also points out that CRUD operations need to be guarded by locking statements)
