Temporary Fix for LavaSlide

[gnavadev]

Replace

    if GetV(V_SKILLATTACKRANGE,myid,MH_LAVA_SLIDE) == 1 then
        if UseDieterLavaSlide and GetV(V_HOMUNTYPE,myid)==DIETER then
            logstring=logstring.."UseDieterLavaSlide disabled - you don't have the skill!"
        end
        UseDieterLavaSlide=0 
    end

With

    if GetV(V_SKILLATTACKRANGE,myid,MH_LAVA_SLIDE) == 1 then
        if UseDieterLavaSlide and GetV(V_HOMUNTYPE,myid)==DIETER then
            logstring=logstring.."UseDieterLavaSlide disabled - you don't have the skill!"
        end
        UseDieterLavaSlide=1
    end

In some servers like RagnarokLatam lavaslide isn't working, this is not the right fix, but it's the best workaround I could find with my limited time.
