Subject: Drop all locking of part.TaskInventory in favour of a
 ReaderWriterLockSlim lock handler. This gives us:  - Faster prim inventory
 actions. Multiple threads can read at once.  - Fixes the known prim inventory
 thread locks  - In the event of a thread lock occurring, it will usually self
 heal after sixty seconds with an error message in the console
