Dual addon mounting (#188)

* yip

* More WIP

* Update build scripts to use hl2sdk-manifests

Now using the proto files included in the sdk, except for the cs ones which are broken for some reason

* Dockerize build process

* mount source instead of copying

* Use a different detour to mount addons

* Only add extra addons when changing levels

* More WIP

Now without the silly timer!
serversideclient.h was taken from Wend4r's sdk fork and edited, it should be cleaned up in the future

* Use a Steam ID/IP pair to check for reconnect

Also fix a crash when changing maps

* Remove the Notify detours

Valve has gracefully fixed the auth issue so now we just need to use Hook_ClientConnect for our setup

* Update CServerSideClient layout

* Use a timestamp when checking for addon

* Update build script

* Update sdk

* Removed unused sig

* Fix saving infractions

It broke for some cursed reason that I haven't figured out so I'm settling with this

* fix 2 heap overflows

* Use a different method to get pending clients

It's ugly but it ensures that we won't run into issues with clients sharing an IP

* Some cleanup

* Amend the heap overflow fixes

GameConfig will need a bit of a rework but that doesn't belong in this branch, we've bloated it too much already.
