SpawnPoint

The specific changes include:

Source Engine

* Fixed a bug in networking that would cause long stalls (up to 10 seconds) when a split packet would not be reassembled properly, which forced a full update to all clients
* General optimization to tracelines
* Fix for broken .dem file playback
* Added backward compatibility code to allow demos recorded with protocol 12 to continue to be playable under protocol version 13
* When showing "WARNING: Connection Problem", now indicate the number of seconds remaining before an auto-disconnect will occur
* Fixed a bug that would cause NULLNAME to be shown as the player's name in the scoreboard for a short time

Team Fortress 2

* Fixed exploit where spectators could spawn into the world without actually joining a team

Hydro map changes
* Fixed an exploit that would allow players to jump out of the map

Granary map changes
* Cover changes to the first capture points of both teams. Reduces some of the sight lines for defenders, and should make the area easier to capture
* Teams that are holding more points will receive a greater spawn time bonus (spawn timer reduced for the winning team). This should help attacking teams build momentum
* Minor visual tweaks to the BLU side between capture points 2 and 3
* Clipped off a super high (demo pipe jump) perch in the middle area
* Increased base round timer to 10 minutes
* Added windows overlooking the final cap from the capture point 2 building (via new room next to conveyor route)
* Minor changes to lighting in the middle area
* Moved the middle spawn points farther forward (saves 6-7 seconds off a Heavy's run from this spawn to enemy capture point 2)
* Reduced spawn advantage/penalty to a total of -/+ 6 seconds when on the final cap (from 10 seconds)
* Fixed material alignment and model interpenetration issues in home spawn rocket rooms

SourceTV

* Increased default bandwidth rate from 5 to 8 KB/sec for spectator clients
* Increased SourceTV demo buffer size for table class descriptions from 64 to 96KB. Team Fortress 2 was running over this
* Performance improvement for copying unreliable data buffers to SourceTV clients
* Updated the list of events in TF2 tagged for the director to play
