Thanks, lulurun, for a patch that addresses inventory problems that occur

occasionally, but are fixed on restart (issue 1919).
This patch introduces the following changes:
1. when a user teleports out of Region A, remove that user's profile
from the Region A user profile cache
2. when a user crosses between regions out of Region A, remove that
user's profile from the Region A user profile cache
3. the user profile cache's session ID member can now be set (written),
and is updated each time a connection with a new avatar is established (ie: a
new avatar enters the region)
4. when a region server looks up a user profile and a cache miss
occurs, fetch the user profile from the user server first instead of
immediately returning null
