Counter-Strike: Source bug fixes

Fixes crash in filter_activator_*->TestActivator() when activator isn't valid anymore.

Fixes game_ui lag and player_speedmod turning off your flashlight.

Patchnotes

Thanks to the leaked Source Engine 2007 sourcecode.

File: se2007/game/server/game_ui.cpp

Line 292:

void CGameUI::Think( void )
[...]
	pPlayer->AddFlag( FL_ONTRAIN );
[...]

Replaced pPlayer->AddFlag( FL_ONTRAIN ); with NOP to fix prediction issues while having game_ui active.

File: se2007/game/server/player.cpp

Line: 7587

void CMovementSpeedMod::InputSpeedMod(inputdata_t &data)
[...]
			// Turn off the flashlight
			if ( pPlayer->FlashlightIsOn() )
			{
				pPlayer->FlashlightTurnOff();
			}
[...]

NOP'd out the block.

Configuration

In cstrike/cfg/server.cfg add this

//============================================================================
// Late load support - since multiples things need to be init before load it
// The upcoming extensions can not use autoload file
