Spoike f33873ddb7 committing for fixes for OMC
some minor changes. Mostly bug fixes and internal reorganisation.
Added code to provide an activex control as part of the npfte.dll plugin. If the dll is registered the regsvr32 way, the plugin can be used with IE as well.
fisheye/panoramic view enable is now controlled by rulesets instead of serverinfo.
server will list all pak files it has loaded. client will probably do the wrong thing and still needs fixing properly.
