[HLDM] bhop unleashed

In vanilla HLDM, bhop is blocked. Usually servers unlock it with Metamod. But it is possible to enable it without any mods - just patch "hl.dll" directly.

Use BugfixedHL client to avoid jittering: it can detect if bhop is allowed on server https://github.com/tmp64/BugfixedHL-R....
Or use my valve_addon pack that includes the BugfixedHL client along with detail textures and BM:S models https://github.com/raub/valve_addon/r....
