Subject: 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
