* 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..
When fatal is set, the function will show a error dialogue, which will halt the process and close when the message is dismissed. Else we will end up in a crash.
* Fix all compiler error for GameSDK on S0 and S1.
* Remove some unused patterns and globals (launch performance gains of 100ms).
* Remove most duplicate patterns.
* Relocate globals from engine to a more appropriate location.
* Renamed some unknown vars to a more appropriate name (most of these where obtained a while back, but as we reversed more parts of the engine, some of these vars become known).
* Renamed some vars to fit the naming convention used in the SDK.
* Fixed pattern debug logging using the wrong pointer, thus displaying the wrong address.
running "script_client" from main menu would cause an access violation when attempting to access m_hVM from the CSquirrelVM instance for the client vm, which has not been created by this point
The game uses 2 types, CSquirrelVM (mostly exposed to the VScript API of the engine) and HSQUIRRELVM (mostly used for internal squirrel functions like sq_pushbool etc..).
This refactor properly splits the CSquirrelVM* functions from the HSQUIRRELVM (SQVM*) ones. The functions have also been renamed accordingly and the prototypes have been adjusted to use the correct pointer type.
