[FIX] ZConfiguration PrimaryWeapon not saving

[Guilherme IA]

When you change primaryweapon (late dash config), not saving. This is the fix for it. (from 1.5)

Search for bool ZConfiguration::LoadConfig(const char szFileName)* and change:

actionKeyElement.GetAttribute(&nKey,"alt",-1);
    if(nKey!=-1)

to:

actionKeyElement.GetAttribute(&nKey,"alt",-2);
    if(nKey!=-2)

Iirc, _ASSERT is only executed in Debug builds.
They should not get executed in any of the Release builds(including RelWithDebugInfo).

You should keep this uncommented for development purposes in Debug builds.
