[Simian] * Made default assets for map water overlay and HyperGrid portals * Fixed asset store loading regression * Start synchronization after RegionHandshakeReply instead of CompleteAgentMovement (allows the sync function to be called for child agents as well) * Start informing clients of neighbor regions when AgentThrottle is received (prevents client crashes, and this will become necessary data in the future) * Minor fixes in map handling git-svn-id: http://libopenmetaverse.googlecode.com/svn/libopenmetaverse/trunk@2488 52acb1d6-8a22-11de-b505-999d5b087335
