Windows deps: Fix linking when building ogre first with rel/relwithdebinfo and then with debug. If you built debug first it would have worked as the Ogre cmake did not find the libs in /Dependencies/lib/Relese, /Dependencies/lib/Debug were never deployed correctly, instead deploy happened to /SDK/lib/Debug which is now given to Ogre cmake as the first place to look for them.
BuildDeps: Move to Assimp 3.1, not yet released but will be very soon from head. We can update to the official tag later.
SyncManager: Fix buffer overflow bugs in both reading from and writing to the network. The actual buffer sizes used for network message remain unchanged, the sizes were only made internally bigger to fix overflow and to implement checks after attribute serialization without corrupting the buffers. Same 16*1024 is still the cap that gets sent to the clients/server. These checks can be removed once clients have updated and is kind of a Meshmoon spesific work around. In core Tundra these checks can possibly be removed and the changelog needs to say to update both clients and servers at the same time, for Meshmoon this is not possible without denying old clients access to servers completely. Minor tweaks and improvements to the pending logic to remove unneccessary pending entity bookmarking.
