[PATCH] fix xvid_plg_data_t fields documentation

Hey,

Just a very small patch to the documentation in xvid.h, namely the 
fields bquant_ratio and bquant_offset of struct xvid_plg_data_t which 
are listed as "[in]" (written to by the plugin) but should be "[out]" 
(read by the plugin).

I haven't updated the Changelog since the change is insignificant.

Diff is below.

Thanks,
delthas
