RCON implementation (see description) * Fully rewritten protocol agnostic CNetAdr class * Fully rebuilded legacy CNetAdr class * Fully rebuilded dual-stack CSocketCreator class * New project "netconsole" added (lightweight netconsole for RCON) RCON is still work in progress

Partial CNetChan class rebuild and implementation (see description) * Adapt codebase to new class to reduce rune-like code. * Fixed several bugs where the global CClient pointer was used instead of the instance in question to issue bans and display information about a certain client in CBanSystem and Pylon. * Upgraded CBanSystem and Pylon to use IPv6 instead (including IPv4 mapped IPv6 addresses). This breaks all existing banlist files! All bans have to be re-issued or the existing file has to be updated to use IPv4 mapped IPv6 addresses and renamed to 'banlist.json', and moved to the root of the 'platform' folder.

Improve threading (work in progress) * Only run '_DownloadPlaylists_f()' in the main thread, schedule for next frame if we aren't in the main thread. (this should fix crash cases related to disconnecting from the game). * Locked read/write to CBrowser members (thread for obtaining the server list is detached, but once the 'slow' post operation in this thread is complete, mutex lock is acquired (locking the render thread if the browser is active) to set the string members of CBrowser, this operation is very fast as we only set the string and the color after the http post operation (this never caused a crash, but the behavior without any lock mechanism is technically undefined regardless). * Obtain the host name dynamically from the ConVar 'pylon_matchmaking_hostname' (atomic operation). Initial approach was deleting the whole master server pointer just to construct a new httpclient object..

Partial CNetChan class rebuild and implementation (see description) * Adapt codebase to new class to reduce rune-like code. * Fixed several bugs where the global CClient pointer was used instead of the instance in question to issue bans and display information about a certain client in CBanSystem and Pylon. * Upgraded CBanSystem and Pylon to use IPv6 instead (including IPv4 mapped IPv6 addresses). This breaks all existing banlist files! All bans have to be re-issued or the existing file has to be updated to use IPv4 mapped IPv6 addresses and renamed to 'banlist.json', and moved to the root of the 'platform' folder.

string g_svNetKey = DEFAULT_NET_ENCRYPTION_KEY;
Code overhaul Moved every pattern to IDetour interface. This allows for debugging patterns scans more easily, and create threads during pattern searching (Operation is now fired in APIENTRY). Also cleaned up some unused code/extraneous comments. Slightly increased performance by purging duplicate patterns. Made variable search less dependent from other results (except if pattern-to-scan results is within the same header)
