Spoike c1e991f31c hide console while updating packages. 
fix rate indicator with http downloads.
fix gamedir change crash.
force r_shadow_realtime_world_lightmaps to 0 if there are no rtlights on the map (to work around TF/etc maps where such 'useless' entities got stripped).
tweak profile lists to be slightly more verbose.
add extra parms to fteextensions.qc, so that people realise that fte actually supports that.
