PlutoIW5 support for the Game Interface and improvements to the GSC part of it. (#242)

* Improvements to the GSC part of the Game Interface
* Adds compatibility with PlutoIW5 with minimal changes.
* Fixes issues when commands are called from the web interface when the used profile is not on the server.
    * New Debug output when the target or origin of a command is sent by IW4MAdmin but not found in-game.
    * Commands that can be run on the context of the target are now run in it.
* Simplifies the command registration and execution.
    * Got rid of the huge switch block.
    * Introduced AddClientCommand to register new commands for example
        * `AddClientCommand("SwitchTeams",  true,  ::TeamSwitchImpl);`
        * `AddClientCommand("Hide",         false, ::HideImpl);`
    * Callbacks are called with the full event object and the parsed data as parameters to allow maximum flexibility.
* Introduced level.eventBus.gamename to know which game we are to add minor changes.
* Changes - noclip/lockcontrols/playertome
Additional changes to support other games' functions

+# Game Interface
+
+Allows integration of IW4M-Admin to GSC, mainly used for special commands that need to use GSC in order to work.
+But can also be used to read / write metadata from / to a profile and to get the player permission level.
+
+
+## Installation Plutonium IW5
+
+
+Move `_integration.gsc` to `%localappdata%\Plutonium\storage\iw5\scripts\`

+
+Move `_integration.gsc` to `IW4x/userraw/scripts`, `IW4x` being the root folder of your game server.
